NesdaOHIO Takes a Field Trip
Whether it was caused by a case of The Winter Blahs or Cabin Fever or just a case of nesdaOHIOANS glad to come out of hibernation following a Long Winter the March meeting of nesdaOHIO was held in Chagrin Falls, Ohio a charming town on the Chagrin River about 20 miles east of Cleveland. Named for multiple waterfalls on either side of Main Street, it boasts a picturesque Town Square (more of a Triangle) and the Huge Lowes Electronics store located just off the square in the center of town. We mean NO not THAT Lowes NesdaOHIOs own Bob Lowe who has been a Fixture in Chagrin Falls for over 50 years. Picturesque as it is, none of those items is the Big attraction to the town Rather it is Bob Lowes Cousin Trixie, known to all nesdaOHIOANS (Some more than others) and to readers of this newspaper. Were forced to say that the meeting started a little Late, and not just because of the Free Pizza provided by NesdaOHIO.

Bob Lowe graciously opened his store to us nesdaOHIOANS for an evening of Technical Training on the new Digital Cable Boxes. Whats to know about a Cable Box?, you ask. Well More than you would think with these Digital Boxes, and Bobs son Kevin was there to show that he is Truly an expert in the setup of these boxes. Based on what This Reporter saw that night He would bet that only a small fraction of Digital Cable Boxes are set up properly for their owners. Thats Not So with Customers of Lowes Electronics, for Kevin is able to access the Hidden Secret Menus of these boxes Newsletter Hotline ! and set up the options so that the customer receives the true Got A News Item ? performance of the box.

Kevin says that he has been to many houses where the Cable Man set up the customers HD Digital Cable Box (for which the customer was paying Extra to the Cable Company) via the RF Inputs to the Television and That Sure aint Hi Def! Throughout the meeting Kevin demonstrated how to access the features in the hidden setup menus of a Time-Warner Scientific Atlanta Digital Cable Box that is used throughout Northern Ohio. You Dont get there just by pressing the Settings button on the remote. THAT gives you Basic Customer Settings To access the Special Options Kevin showed that you hold down the INFO and Guide Buttons on the box for 5 seconds to make the hidden menus appear. Then, he showed how to make the box do a Factory Reboot in case things have gone awry and need to be completely reset. He went on to show how to set the Aspect, and the Resolution. He showed how to make the box Autoselect the proper settings for the various HD formats, and he even told of a couple problems that can be caused by Improper settings resulting in a Pink Screen, No Color, or a Terrible picture as shown on the set in the accompanying photo. The Digital Cable Boxes are a lot more complex than many of us thought, and Kevin said that you really have to evaluate your customer and tailor the options to the person. An Older person (That describes most nesdaOHIOANS was He Talking about US?) is interested mainly in Ease of Operation, while a younger customer would want every Whiz-Bang feature on the device Enabled. Because of a Fine training session presented by someone who deals with these installations every day, we are now much more familiar with what we thought was an easy subject but isnt. Thank You Kevin ! NesdaOHIO Thanks Bob Lowe for his Hospitality for inviting us to his store for this Very Interesting session. And Thanks to Trixie, too.

Letters We Get LETTERS

EDITORS NOTE: We enjoy hearing from our readers here at The Speaker. Oftentimes, a reader can add additional information to an article written by another, and increase our collective store of knowledge. In a recent letter, Mark Wentowski of Perry Hill Electronics Service in Montgomery, Alabama , writes concerning an article in the March issue of this newspaper. That article, covering a Vizeo LCD model L32 with a symptom of Wont Power Up has Amber light only suggested 3 possible fixes to the Reset Circuit. (Refresh your memory by re-reading Page 5 of the March issue at www.nesda-ohio.com) Mark Says: In the article "Raising the Dead" by Jim Knoble I could mention that version #3 of the repair should require that the anode of the diode be connected to pin 2 and the cathode to pin 3. The first time I tried to do it I installed the diode backwards and it didn't work. [Note: Jim had no data about the polarity of the diode. Mark tried it both ways and learned the correct polarity] He continues: That's the only version of this repair I've ever tried after Jim posted the fix to another service forum a month or so ago. So far, after getting the polarity correct, the diode method has worked perfectly for me on three out of three sets. Otherwise those sets would have met one of three possible fates; #1) Picked up unrepaired by a pixxed off customer. #2) Be donated to us to cull out for spare parts. #3) Get thrown into the dumpster. Mark says that although the accompanying figure shows the diode piggybacked onto this reset IC, he opted to REMOVE U26 from the PCB and discarding it when replacing the diode as was suggested in the original fix. The Speaker thanks both of these fine techs for helping our readers.

The Audio Corner

Do you repair Audio? Have you ever repaired Audio? With the times being what they are, perhaps you are beginning to take in Component Audio Systems for repairs when you never have before and discovering that they pose their own Special problems that you dont see within the sound section of a TV set. If that describes you, then were glad that you stopped in this corner for a visit. Well talk about Receivers, Tape Decks, CD Players, Turntables, and many products that most pointedly do NOT have an imaging screen. If you Dont do audio, well, just wave as you pass us by and go lip-read somewhere else. Todays Topic: DOUBLE TROUBLE SANSUI 9090DB The arrival of todays Sansui 9090DB Stereo Receiver was prefaced by a Huffing & Puffing of a Locomotive coming up my sidewalk. It wasnt until the customer walked in the door and hoisted his product onto the receiving counter that I discovered that the Huffing was coming from Him. He stopped only for a moment before blurting between breaths Just a Minute and then went back out to the Parking Lot. It was only a few seconds before I heard that peculiar sound again, and the customer walks in with a Duplicate of the Sansui he had just Plunked Down. He started to tell of his problem, but then had to stop to catch his breath. For a moment, I thought that I was dealing with Monseuir Joey who is found in the Poertry Corner of this newspaper. What a Wimp! Im thinking. Guy cant even carry in his Receiver. As it turns out, both of these receivers had No Sound (Not surprising, since this is The Audio Corner) but they each had their own Presentment of that problem. One showed a continuous flashing of the Protect Light, while the other showed a Green (ok) Protect, but had no sound or dial lights. Since the Basic principle of troubleshooting is the Divide & Conquor approach, I did Just That. I Picked One of these units up and carried it to the Workbench and discovered Why that guy was Huffing & Puffing. This Thing Is HEAVY !!!! There is a Big Ol Power Transformer that is a Six-Inch Iron Cube. It alone must weigh 15 Lbs! Then this has a Steel Chassis, a Pressed Wood Cabinet, Lots and Lots of Discrete components scattered among A Dozen Circuit Boards. LOTS of Boards Both on the Topside and on the Bottom Side. There must have been a Phenolic Surplus the year this thing was made. The Specs say that this thing weighs in at 59 Pounds, and I felt every one of them. This receiver was the one that had No Sound, and No Dial Lights. I ignored the Dial for the moment, and measured the B+ on the

collectors of the Output Transistors. (Eight TO-3 type transistors) and found that I had a +33 & -33volts on the collectors. That struck me as unusual, for such a heavy Behemoth and indeed it WAS Rated at 85 Watts per channel, so I looked a little closer into that Power Supply. Fortunately, there Was a schematic available at the Hi-Fi Engine (www.hifiengine.com) and I downloaded that in a Trice. The Schematic called for a + & - 65v on those collectors and here I had only Half of that. Well, I have been Faked Out by That before, so I looked a little closer at that Power Schematic. I sure didnt want to turn into Monseuir Joey who writes about being faked out during a repair. Sure Enough, there was a Power Changeover Block that switches the receiver from 120v to 240v operation. Sansui cleverly hid that behind the Nomenclature Plate, but I was able to find it and put it back to where it was supposed to be. Ya Wonder just how things like that can get moved around. The + & - 65volts came up, and I was now able to drive sound through the Output stage but still there was No Tuner Sound present. There was No B+ present on the Tuner or the IF Boards. I did some more Measuring, and Signal Tracing, and looking around with no success, and was just getting ready to take a break and attack the Other unit when My Eye fell upon : The Equalizer Board F-2653. This Board is on the Topside of the chassis, sitting at the Front-Right Corner. It contains among other things the Function Switch, and Three Harness Plugs. Can you see it? Squint Real Hard The Middle of those 3 plugs is a 5 Pin Plug sitting on a Six Stake Connector (See the extra Pin sticking out on the right?). The Plug next to it towards the Bottom of the figure is a Six Pin Plug sitting on a Five Stake Connector. Do you see a Pattern Here? First the Power Changeover Plug is in the Wrong Place, and Now 2 Harness Plugs are Transposed. I am beginning to wonder if the customer might have had a hand in this (Pun

Intended).

Well, Yes He Did, as I discovered when I Inquired at time of pick-up. He Could have admitted beforehand that All I wanted to do was clean the controls which is what he said when I strapped him into the Interrogation chair. A few minutes with a DLP Lamp shining in his face and he cracked like a Ripe Melon and spilled the Beans about his transgression.

Putting those 2 plugs back where they belonged brought back the sounds like Gangbusters oops sorry, wrong decade. These Sansuis have a Very Nice sound to them and they played very well through the shops Thunder Lizard Speakers. One last thing: The Dial Lights? Well, they had a bad fuse in the 6 volt AC line. This sucker has 9 Fuses scattered through it, both on top of the chassis and on the Underside. Once the fuse was replaced and 3 Fuse lamps replaced, This Boat-Anchor was Done!
of the day would have read Toasted Speaker. Each PNP and NPN Output Transistor was measured for a shorted Junction, but all were found to measure Good. HMMMmmmm No, that wasnt the amplifier Humming That was me Thinking. Specifically, I was thinking: If it aint The Outputs, then maybe its the Drivers, so I dutifully measured all of the transistors on that side of the Driver PCB and compared them to the Good side. To my surprise, None of the Drivers measured Shorted, either. Well, What a Revoltin Development THIS is! But maybe its a blessing in disguise. Although the 40 year old transistors ARE available at B&D - The Semiconductor Specialists - for only a few bucks, if one of those 15 Amp Outputs DID short, there would likely be some ancillary damage to the surrounding circuitry. It might be worth having to do some extra cogitating to avoid changing an ashtray full of components.

DOUBLE TROUBLE Part Duex

Do you repair Audio? Have you ever repaired Audio? Well if you werent asleep when you read the article above, you would have vicariously fixed the Sansui already. As you can see, dedicated Audio equipment Does have Special problems that you dont see within the sound section of a TV set. I hope youll stick around for a few more paragraphs to read about Part Two about these Double Receivers that do NOT have an imaging screen. If you Dont do audio, well, just wave as you pass us by and go lip-read somewhere else. I Said that the customer brought in TWO of these Sansui 9090DB Stereo Receivers. Well This is the Second of those fine products, and if the performance of the first is any gauge, I should be in for some good listening in a little while. This product presented a somewhat different problem than the previous. On This, the Dial Lights and the Tuner Indicators were active, but there was No Sound. That was to be expected, since the red Protect light was flashing, and you never heard the Speaker relay click. It was assumed that the problem was in the Power Amplifier Output stage, and voltage measurements on the collectors - all eight of them - were performed (Two transistors are paralleled in each channel for current handling capability). The Transistors are TO-3 cases mounted on the Rear Panel so it was easy to determine that +65 and -65 volts was present on e a c h tr ansisto r. Then, the next check wa s to measure the center point voltage of each output Pair (The point where the PNP Emitter and the NPN Emitter are tied together through two.33 resistors). This is the point that is fed to the Speakers and is monitored by the Protection circuit for any B+ being present on the speaker line. Its a good thing that it was being monitored, because there Was -65v present on that Speaker line. If the Protection circuit had not been doing its job, the Menu

I put a headband around my forehead (My head
swells forced when Im to Think),
Then removed the Driver PCB and held it in my h a n d Sometimes I can feel Paranormal Vibrations when I do that. I
recited Ohms Law near the input to the Driver board, and rubbed it with my CET Certificate. Then I reached for my Meter. As I stared at the PCB I could feel the emanations calling to my meter probe. They said Measure R33. I applied the meter probes to that Resistor at the lower-right corner of the PCB and measured 40 Meg. You may call me cynical, but I Really doubt that the engineer intended for a 40 Meg resistor to be at that location. I had a ready basis of comparison on the Other side of the circuit board. The Left Channel is a mirror image of the Right channel, so all I had to do was measure R34 on the other side to determine what it Should read. The schematic confirmed that it should be a watt resistor. This resistor feeds B+ to the emitter of a PNP Driver, and with it open the bias to the outputs is Screwed Up (I Love that Technical Talk). A replacement was soldered in and the Centerpoint voltage Re-Read once the PCB was reinserted into the circuit. Now, the voltage was Zero on the speaker line and the pleasant sound of a relay click was heard after a few seconds. With the station tuned to the local Big Band Station, Benny Goodmans Sing-Sing-Sing was heard through the Test Speakers. A little Tweaking of the Idle Current, and this Sansui can join its brother Boat-Anchor in the Outgoing Rack.

GRAND ROUNDS

A continuing feature here at "The Speaker" suggested by the practice used by Doctors in large teaching hospitals to distribute information about case histories. We actively solicit information from YOU, our readers, to be presented here for the benefit of all. Please send your submissions via email to jsopko112@aol.com. Today's Case History: The General Practitioner Sometimes the practice of Television Medicine requires the use of Specialists. There is no substitute than the skills of a person who works on the same product every day and is able to know every nuance of the item. The productivity and quality of repair that the specialist provided would be very great. The downside would be if he ever encountered "something" outside of his field of expertise: A Camera Tech who was called on to repair a Television, for example. THEN, it requires a General Practitioner. The General Practitioner must be able to see ALL the problems and apply his skills to effect a cure for ALL the symptoms. Most of us are General Parishioners. Unless you have the luxury of having a stable of interns, you just can't specialize in one item. You have to attend to whatever walks in your door, as in this Zenith 32", Model SY3272, of 1997 vintage that was carried in by his loved ones. The Patient was Moribund. Not a sign of life, Not a Sound, He was In a complete Coma. Preliminary tests indicated only the faintest flicker of activity in the Primary Power Supply: The Raw B+ was present on the main B+ Capacitor. Please note that with all other circuits Non-Conducting, there is No Load on this main B+ Supply and the charge remains on that B+ capacitor for quite some time after the plug is pulled. That would be quite a surprise, and an unpleasant one if you were to apply your ESR meter across it. The prudent fractioned should Discharge the unloaded supply before making passive tests in the power supply. Dr. Dick Smith of ESR Fame would certainly second that motion! One of the first tests would be for shorts on the STRS53041 Regulator IC (ICX3431) and it's driver Transistor. This is a variation on the familiar circuit that has been in use in Zeniths for Eons. A New Wrinkle is the change of the Driver Transistor QX3401 from the smaller type TO92 case to the Larger and Flatter TO126 cased 2N4923. No shorts were shown on the IC, but QX3201 was shown to be shorted. The two components were replaced as a pair, and power reapplied - - - with no effect ! Sometimes the Operation is a success, but the patient still suffers from Complications.

By: Joe Sopko CET The Complications require additional treatment. There was a Slight change in symptoms produced by the component change in that a slight feeble "Chirp" was now head upon Plug-In. In this case, ESR Tests were performed on the Electrolytic capacitors in & around the SMPS circuit. CX3416, a 100UF @ 25V Capacitor adjacent to the Heat Sink was found to exhibit high ESR. A Cap-ectomy was performed with expectations of a cure, but once again the practitioner was faced with disappointment. The Patient still languished in his hospital bed with no sign of life. A close Physical examination was performed - in greater detail that the preliminary check that was made upon admission. The PCB showed signs of overheating in the area of the SMPS, so Point-to - Point resistance measurements were taken from each pin of the STR53041 to the next point on the conductor. An open was found off the IC's Pin 2 along the foil, and a repair to the PCB was made at that point. The Operating Room was filled with all manner of nurses & interns who were breathless with anticipation as power was reapplied. This time, the GP's skills were rewarded by the Normal Robust Chirp of the SMPS upon Plug-In and the crackle of HV as the power button was pressed. Picture & sound reappeared, and the patient went on to live a normal and productive life In the age of the Specialist, sometimes a General Practitioner is needed who can apply his skills to ALL the disciplines in order to effect a cure.

The Computer Illiterate

By: Joe Sopko Sopko
A Continuing Feature at "The Speaker", written by an acknowledged Computer Illiterate. The material contained here may be known to everybody in the civilized world - except the author - who says "It sounded good to Me, so I'll pass it on". The author advises that he has NO knowledge of computers, and as such cannot judge the accuracy or efficacy of the material presented herein. Nor does he assume any responsibility for damage to your computer, files or self esteem.
Todays Topic: REAL Help from The Computer Illiterate Sometimes I wonder if I am of any real help to people in this column I mean, What I know about Computers would barely fill a thimble. I believe that the Lord High Editor of this paper only publishes this column for some Comic Relief so that you could laugh at me as I do battle with these mechanical Spawn of the Devil. Well, TODAY, I am going to offer some REAL help on a REAL problem that I just encountered and Whats more, I Solved it Myself! The problem wasnt with the computer on my desk; rather, it was with the Thumb Drive that I stick into it. (I Know, you Thought that Patti Murtz grabbed every Thumb Drive East of the Mississippi, but I must have beaten her to THIS one). This little 1 Gig Memory Stick developed a Corrupted File (actually TWO Patti Murtz files) that just Couldnt be deleted by normal means. I have NO idea how this happened, and it didnt really cause me a problem because I could access every Other file on that stick, but I just couldnt delete either or both of those two files. I even tried dragging them to a new folder on that drive, then deleting the folder, but that didnt work, either. Whenever I tried to delete it (them) a message would come up that said Corrupted file Unable to Delete and then both of those files would still be there the next time I looked at the directory for my (G:) thumb drive. After the 47th attempt at deletion, I gave up. I Hate That I really DO hate computers, because they really dont work the way that you think that they should. So WHAT if these files are corrupted THATs why Im deleting them, You Mechanical Moron !!!, I said to the Devils Spawn. That was about as effective as anything else that I do with computers, so I was thinking about driving down to the East Ninth Street Pier and flinging this %$# memory stick into Lake Erie as far as I could throw it. The only thing that saved it was the high price of gasoline.

The other thing that saved it was some Googling that I did. I have to admit that I have embraced Google Big Time, and it saved the day in this case. I came across a posting that another unfortunate computer illiterate had made on a Blog (I guess thats what theyre called). In it, he described a situation that sounded very similar to mine only HIS undeletable file was on his main Hard Drive. The reply that he got solved his problem, so I was hopeful that it would solve Mine too. The GURU that helped the online poster wrote: Open a dos prompt window, and type "chkdsk c:" (or chkdsk d: depending if your file is on C: or D: or E:) It will tell you "you did not provide the /f flag, I will only look without repairing". No problem, let it look, and if it says "no errors", then chkdsk is not the solution. If it finds a problem, run it again with the /f option, like this : chkdsk d: /F To which I said HUH?. I hate it when they speak Computerese I had to give this a great deal of thought before I could even try anything. Finally, I went to the START button, then RUN and typed CHKDSK G: in that box. When I clicked Enter a DOS Box opened, and some stuff happened, and it looked like it was checking my G (thumbdrive) because the light on it was flashing, and then it stopped and suddenly The Dos Box Disappeared. Hey, I couldnt even read what it said It was there and gone so fast. So I Brought up the drive menu once more to see if it actually DID anything, but to my dismay, those two undeletable files were still there. I wasnt even disappointed any more I have come to accept defeat when I try things on computers, but I didnt give up this time. I remembered seeing a Command Prompt selection on a menu somewhere sometime. As I have been faked out so many different ways on computers, I have looked in a LOT of different areas of this $#$# machine.

Cont. next page, Pg. 13

Page 12
Cont. From Previous Page,
I Clicked on START, then PROGRAMS, then ACCESSORIES, then SYSTEM TOOLS, and then Right there in plain sight was a selection marked COMMAND PROMPT. I clicked that Tuite Sweet and a Big Black Box came up in the middle of my screen. It looked like the photo below, right. Thats a Command Prompt, all right. I seen one once, somewhere. Since I am the youngest of the nesdaOHIOANS, I never used computers back in the Olden Days of DOS computers, but I remember seeing this in a museum somewhere. The best thing with this big black box was that it STAYED on the screen. Now, I was able to type in my CHKDSK G: in there without it disappearing! It did its thing while I sat around making disparaging remarks, and when it was done, it said that it did Indeed find 2 file errors. I have to admit that I wasnt impressed; after all I KNEW that there were 2 file errors there I was doing THIS good by myself. But then I went and did what that online Computer Guru told that other guy. He said that if Chkdsk finds errors, to run it again with the /f option, like this : chkdsk d: /F so thats what I did. I typed into that DOS box chkdsk G: /F since mine was on the G Thumbdrive and watched it do its stuff once more. NOW, when it was done I went and viewed the thumbdrives directory and WALLABALLOO!!! The Offending Corrupted Files Were Gone !!!

Oh, my Joy knew No Bounds !! I cant believe that I actually solved a computer problem! OK OK, youre saying that I didnt solve it, the online Computer Guru really solved it but I dont care. It was MY fingers doing the typing, and it was MY eyeballs that did the Googling, and I am going to grab whatever credit I can from that. So, to Summarize: Ya got a Corrupted File that you cant delete? Open a Dos Box and tell Chkdsk to fix it with a /F suffix chkdsk G/ F Thats all there is to it !
