Attention: This service manual is only for service personnel to take reference with. Before
servicing please read the following points carefully.

Safety instructions

1. Instructions
Be sure to switch off the power supply before replacing or welding any components or inserting/plugging in connection wire Anti static measures to be taken (throughout the entire production process!): a) Do not touch here and there by hand at will; b) Be sure to use anti static electric iron; c) Its a must for the welder to wear anti static gloves. Please refer to the detailed list before replacing components that have special safety requirements. Do not change the specs and type at will.
2. Points for attention in servicing of LCD
2.1 Screens are different from one model to another and therefore not interchangeable. Be sure to use the screen of the original model for replacement. 2.2 The operation voltage of LCD screen is 700-825V. Be sure to take proper measures in protecting yourself and the machine when testing the system in the course of normal operation or right after the power is switched off. Please do not touch the circuit or the metal part of the module that is in operation mode. Relevant operation is possible only one minute after the power is switched off. 2.3 Do not use any adapter that is not identical with the TV set. Otherwise it will cause fire or damage to the set. 2.4 Never operate the set or do any installation work in bad environment such as wet bathroom, laundry, kitchen, or nearby fire source, heating equipment and devices or exposure to sunlight etc. Otherwise bad effect will result. 2.5 If any foreign substance such as water, liquid, metal slices or other matters happens to fall into the module, be sure to cut the power off immediately and do not move anything on the module lest it should cause fire or electric shock due to contact with the high voltage or short circuit. 2.6 Should there be smoke, abnormal smell or sound from the module, please shut the power off at once. Likewise, if the screen is not working after the power is on or in the course of operation, the power must be cut off immediately and no more operation is allowed under the same condition. 2.7 Do not pull out or plug in the connection wire when the module is in operation or just after the power is off because in this case relatively high voltage still remains in the capacitor of the driving circuit. Please wait at least one minute before the pulling out or plugging in the connection wire. 2.8 When operating or installing LCD please dont subject the LCD components to bending, twisting or extrusion, collision lest mishap should result. 2.9 As most of the circuitry in LCD TV set is composed of CMOS integrated circuits, its necessary to pay attention to anti statics. Before servicing LCD TV make sure to take anti static measure and ensure full grounding for all the parts that have to be grounded. 2.10 There are lots of connection wires between parts behind the LCD screen. When servicing or moving the set please take care not to touch or scratch them. Once they are damaged the screen 1
would be unable to work and no way to get it repaired. 2.11 Special care must be taken in transporting or handling it. Exquisite shock vibration may lead to breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong case before the transportation or handling. 2.12 For the storage make sure to put it in a place where the environment can be controlled so as to prevent the temperature and humidity from exceeding the limits as specified in the manual. For prolonged storage, it is necessary to house it in an anti-moisture bag and put them altogether in one place. The ambient conditions are tabulated as follows:

Temperature humidity

Scope for operation Scope for storage Scope for operation Scope for storage
0 ~ +50 oC -20 ~ +60 oC 20% ~ 85% 10% ~ 90%
2.13 Display of a fixed picture for a long time may result in appearance of picture residue on the screen, as commonly called ghost shadow. The extent of the residual picture varies with the maker of LCD screen. This phenomenon doesnt represent failure. This ghost shadow may remain in the picture for a period of time (several minutes). But when operating it please avoid displaying still picture in high brightness for a long time.
3. Points for attention during installation
3.1 The front panel of LCD screen is of glass. When installing it please make sure to put it in place. 3.2 For service or installation its necessary to use specified screw lest it should damage the screen. 3.3 Be sure to take anti dust measures. Any foreign substance that happens to fall down between the screen and the glass will affect the receiving and viewing effect 3.4 When dismantling or mounting the protective partition plate that is used for anti vibration and insulation please take care to keep it in intactness so as to avoid hidden trouble. 3.5 Be sure to protect the cabinet from damage or scratch during service, dismantling or mounting.

LC-23K6 working principle analysis
Please refer to LC-23K6 BLOCK DIAGRAM in order to know the working principle of LC-23K6 brief introdection to its signal flow is shown as follows: RF signal produces composite color television signal through TUNER201, the signal together with AV1/SVHS(SVHS priority), AV2 etc. are sent to U29 VPC3230D to decode and do switching selection. In addition to decode the selected video signal, part of the selected video signal is also sent to AV terminal and 21 line decoder U32 Z86229 which is exclusive to decode CCD/V-CHIP to decode. After decoded by U32, the signal will be sent back to U29 in the form of R G B and FB, then it will be added to the decoded picture and then it will be sent to U13 FL12310 in the form of ITU-R656 signal format of 8BIT to do line-by-line process. Send two ways YPRPB signal to U30 MST9883 through selection by N2 PI5V330 in order to do the A/D conversion. After this, the signal will be converted into YUV signal of 24BIT, send it to FLI2310 also. After a series of procedure such as matrix, chroma and tint etc. by FL12310, the two ways signal will be converted into RGB of 24bit, then send it to the main processing chip U12 JAG-ASM. send RGB signal it to the main processing chip U12 at the same time. There has another signal which should be sent to U12 together with he above two kinds of signal that is: RGB signal of 24BIT produced by DV1 through U15 TFP403/501. do the picture format processing for the three kinds of signal in U12. Firstly do the A/D conversion for RGB signal of VGA, then do the switching selection together with the other two kinds of signal. And then they will be converted into 1024*768 format through digital display processing such as OSD and GAMMA correction etc. output it in the form of 24BIT RGB signal. Send it to LVDS convertor U31 DS90C383A, then it will be converted into signal format which can be accepted by LCD screen namely 3 low-voltage differential signal and 1 clock signal, finally send it to LCD screen to do the picture display PWM of U12 can also be used to control the brightness of back light-source. Send SIF (the second IF) outputted by tuner to audio processor N201 MSP3420; send YPRPB and audio signal of DVI to N201 through switching selection by U34 HEF4052; Send AV1/SVHS, AV2 and audio signal of VGA to N201 also. Firstly SIF will be done the switching selection together with another four ways of audio signal, finally volume control and sound effect processing will be done. Output left-right sound channel signal R/L. one will be sent to SRS sound field processor N203 M62494 to do SRS processing and finally amplified by N213 and N214 MP7720 to drive the speaker, one will be used to drive the headphone through N212 TLE2142 and the last part will be outputted as R/L of AV OUT.

Programming the Polaroid Universal Remote Control
Following are two sets of instructions for programming your Polaroid Universal Remote Control to work with other devices in addition to your Polaroid TV. (If you only wish to use the remote control with your Polaroid TV, no additional programming is necessary.) Begin with the Direct Programming Setup, and if unsuccessful, go on to the Auto Code Search Setup.

Direct Programming Setup

This method requires use of one of the device codes found in the Device Code Table (see last pages of your Operating Manual). Begin with the first code listed for your device. 1 Turn the device power off and point the Polaroid Universal Remote Control at the device you wish to control. 2 Momentarily press a device button on the Polaroid Universal Remote Control (TV, DVD, CBL, or AUX). When you release the device button the red LED at the top of the remote will blink once. Note: For devices other than a TV, DVD, or Cable Box, use the AUX key. 3 Press and hold the SET button (top-left button) until you see the LED blink once, followed by two short blinks. Release the SET button after you see the two short LED blinks. 4 Enter the 5-digit code from the code table for the device you want to control. The LED blinks once each time you press a numbered button. After you enter the last digit: a) If the code you entered is the correct code for your device, you will see the LED blink twice. Go to step 5. b) If the code you entered is not the correct code for your device, you will see the LED blink once. Repeat steps 2-4, this time choosing the next code in the list. 5 Press the Power button (top right-side button) on the remote and your device power should turn on. If the power does not turn on, repeat the entire procedure beginning with step 1. If you are unable to program the remote properly after two or more attempts using the Direct Programming Setup, go on to the Auto Code Search Setup.

Auto Code Search Setup

This method does not require use of the Device Code Table. 1 Turn the device power off and point the Polaroid Universal Remote Control at the device you wish to control. 2 Momentarily press a device button on the Polaroid Remote Control (TV, DVD, CBL, or AUX). When you release the device button the red LED at the top of the remote will blink once. Note: For devices other than a TV, DVD, or Cable Box, use the AUX key. 3 Press and hold the SET button (top-left button) until you see the LED blink once, followed by two short blinks. Release the SET button after you see the two short LED blinks. 4 Press 9 - 9 - 1 on the number pad. Each time you press the number 9 button the LED blinks once. When you press the number 1 button, the LED blinks twice. 5 Enter the following number, depending on the device you are trying to control. When you release the button, you should see two short LED blinks. Cable or Satellite box Press 0 TV Press 1 DVD player Press 2 Audio device or VCR Press Momentarily press the power button (top-right button) and release it. 7 Press the CH+ button, slowly and repeatedly, until the device you want to control turns on. Stop pressing immediately when the device power turns on. Note: If you press the CH+ button too quickly you may save the wrong code, in which case the remote control will not turn the device power on. Start at step 1 and repeat the programming steps again. 8 When the device turns on, press and hold the SET button until you see the LED blink twice. The code is now saved, and the remote should operate properly.
