1. SAFETY INSTRUCTIONS GENERAL GUIDELINES 1. It is advised to insert an isolation transformer in the AC supply before servicing a hot chassis. 2. Potentials as high as 33KV are present when this receiver is in operation. Operation of the receiver without the rear cover involves the danger of a shock hazard from the receiver power supply. Servicing should not be attempted by any one who is not competent with the precautions necessary when working on the high voltage equipment. Always discharge the anode of the tube. 3. When servicing observe the original lead dress in the high voltage circuits. If a short circuit is found, replace all the parts which have been overheated or damaged by the short circuit. 4. Always use the manufacturers replacement safety components. The critical safety on the components marked with schematics diagrams should not be replaced by other substitutes. Other substitute may create the electrical shock, fire or other hazards. Take attention to replace the spacers with the originals. Furthermore where a short circuit has occurred, replace those components that indicate evidence of overheating. 5. After servicing, see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed. 6. When the receiver is not being used for a long time of period of time, unplug the power cord from the AC outlet. 7. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazard. LEAKAGE CURRENT COLD CHECK 1. Unplug the AC cord and connect a jumper between the two prongs of the plug. 2. Turn the receivers power switch on. 3. Measure the resistance value with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on
. the receiver, such as screw heads, aerials, connectors, control shafts etc. When the exposed metallic part a return path to the chassis the reading should be between 4Mohm and the 20Mohm. When the exposed metal does not have a return path to the chassis, the reading must be infinite. LEAKAGE CURRENT HOT CHECK 1. Plug the AC cord directly in to the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 2Kohm 10W resistor in series with an exposed metallic part on the receiver and an earth, such as a water pipe. 3. Use an AC voltmeter with high impedance to measure the potential across the resistor. 4. Check each exposed metallic part and check the voltage at the each point. 5. Reverse the AC plug at the outlet and repeat each of the above measurements. 6. The potential at the any point should not exceed 1.4 Vrms. In case a measurement is outside the limits specified, there is the possibility of a shock hazard, and the receiver should be repaired and rechecked before it is returned to the customer.

Figure 1 X-RAY RADIATION WARNING The primary source of X-ray radiation in this receiver is the picture tube. The chassis is specially constructed to limit X-ray radiation. For continued Xray radiation protection, replace the tube with the same type of the original one.

Press the OK button and STORED will appear on the STORE line. The channel will be stored with the program number you desired. You have now stored the first channel. Use the Program up button to select again CHANNEL and continue the tuning procedure until you have tuned in all the programmes you want or the television can receive. To exit the SETUP menu press the TXT button. Please note The system will displayed automatically on SYSTEM row i.e.BG, L, I, DK depending the receiving broadcasting system of the country. In some countries the broadcasting system can be both in BG/DK or BG/LL.Only the TV sets produced with Pal Secam BG/DK or Pal Secam BG/LL systems can receive both BG/DK or BG/LL broadcasts. Please note If you do not press any buttons for 15 seconds the TV will exit the menu system. Automatic Tuning (Autoprogram) Enter the SETUP menu as before.
Use the Program down button to select AUTOPROGRAM and press the OK button. Please Note: a) On the TV sets equipped with ATS a COUNTRY SELECTION menu will appear. Select the desired country using Program and Volume buttons. Press the OK button to select the country and press the OK button again the Automatic Tuning System regarding the broadcasting system in the desired country. b) On the TV sets without ATS pressing the OK button starts AUTOPROGRAM. When you are sure the aerial is connected properly press the OK button and to confirm it press OK button again. To cancel Autoprogram whilst it is working press the Menu button. As Autoprogram stores a channel it will appear briefly on the screen. Your TV is now tuned and ready to use E. TV SET UP The TV set up is accessed through a menu system. Once you have stored your set up, this is the set up the TV will default to when you switch it on. Please note If you do not press any buttons for 18-19 seconds the TV will exit the menu system. There are three menus; Picture Menu Setup Menu Features Menu

TDA 8357J GENERAL DESCRIPTION The TDA8357J is a power circuit for use in 90 and 110 colour deflection systems for 25 to 200 Hz field frequencies, and for 4 : 3 and 16 : 9 picture tubes. The IC contains a vertical deflection output circuit, operating as a high efficiency class G system. The full bridge output circuit allows DC coupling of the deflection coil in combination with single positive supply voltages. The IC is constructed in a Low Voltage DMOS (LVDMOS) process that combines bipolar, CMOS and DMOS devices. DMOS transistors are used in the output stage because of absence of second breakdown. FEATURES Few external components required High efficiency fully DC coupled vertical bridge outputcircuit Vertical flyback switch with short rise and fall times Built-in guard circuit Thermal protection circuit Improved EMC performance due to differential inputs
