Schema TV THOMSON repair error codes.

France. The history of THOMSON began in 1889.

Company founder Eliu Thomson received a prize at an exhibition in Paris for developing an electricity meter. In 1961, the company released the world's first television with a deviation angle of 110 degrees, which led to a decrease in the depth of the television. THOMSON has opened a picture tube production plant in the city of Piaseczno in Poland. Picture tubes are used both for the concern’s televisions and are sold to the CIS countries. Anticipating the imminent collapse of the CRT CRT market, the Company urgently invests in the development of TFT displays. THOMSON MULTIMEDIA concern includes: BRANDT, FERGUSON, SABA, TELEFUNKEN, THOMSON, NORDMENDE.

TVs are being developed on the same chassis with the same circuitry. The main differences between TVs in design.

Remote control: RCT3003.

To enter the service menu, you must: turn on the TV in operating mode. Turn off the TV from the remote control, and then turn off the network button. Holding the blue button on the remote control, turn on the network button. Do not release the button until a raster appears. Release the blue button and press it again. There is a special section in the menu for storing settings. Exit service mode without changes - button.

10MN79V. Fault: does not exit standby mode. Low level on the processor SDA bus (about 1.5 V). After replacing the ST9291J7B1 / AJM processor (can be supplied with the last letters AIR), the SDA level returned to normal, the diode on the front panel constantly flashes, and does not exit standby mode. I installed a clean memory chip, the TV turned on without any distortion in geometry, color, etc.

51MT11X. Malfunction: the TV does not exit standby mode, although the microprocessor has already switched to operating mode, but the horizontal scan start pulses are blocked. And they are blocked using the chain DF21, RF21, TF21, DF22. If you temporarily disable DF22, the device will turn on with a horizontal strip closer to the upper edge. That is, the malfunction is localized in the frame scan, or rather, the IF01 TDA1771 is malfunctioning.

20MG77C. Fault: the device is in working mode, there is sound, but there is no raster. As the accelerating voltage increases, a vertical bar appears in the center of the screen. Cause: A 0.47 uF x 250 V capacitor in the line of low-deflection coils is faulty. All models on the TX91G chassis. Revision. If the contents of the NVM memory are constantly lost, it is necessary to refine the TV circuit by adding an electrolytic capacitor (47 μF x 16 V) between the JR11 (+) jumper and the IR01 (-) screen.

Chassis ICC7

  Replace TDA8178 with TDA8172. Caught in repair THOMSON, chassis ICC7, frame scan assembled on TDA8178. The new chip was purchased for more than $ 10. But the chip turned out to be sawn with TDA8172. It is not known what to buy, and the native, too, has burned out, I decided to replace it with it. Saving money is too obvious. The inclusion circuit was taken from AIWA-2002. The difference in the microcircuits is in the supply of voltage to the 3rd leg. 65 V is supplied to the TDA8178. This circuit is chopped off (and it has already been chopped off, since J238 (4R7) must have burned out), and leg 3 is connected to leg 6 through an electrolyte (220 μF x 50 V) plus to leg 6. Diodes DF16 and DF18 from 3 legs to solder too. Connect foot 10 to the foot 7 with a capacitance of 10 μF x 50 V minus the ground and through the divider 30 * kOhm (top) - 3.6 kOhm (bottom) apply 24 V. Solder capacities and resistors from the print side.

3. Press and hold the buttons on the front of the TV and turn on the TV with the network button on the front of the TV. Do not release the buttons until the TV turns on (approximately 8–9 s). If the central processor detects an error during the initialization process, the TV will not turn on.

In this case, the LED on the front of the TV will flash cyclically. It looks like this. Code 27: 2 flashes, second pause, 7 flashes, two second pause.

All models are on the ICC17 chassis. Fault: the TV does not turn on from standby mode. Failure of TP71 as a result of sparking. All models on the ICC17 chassis with PFC function. Fault: failure of the transistor BUH516TH16 in position TP50 (max, current 8.0 A). Reason: insufficient power reserve. Solution: 1. Replace TP50 with BUH1215 (max, current 16 A). 2. Replace the RP55 from 10 kOhm to 8.2 kOhm.

25DG16ET. It does not enter the operating mode. High and all voltage is normal. The LED on the front panel displays error code 26. Apparently, the kinescope is hooked. On the circuit board of the picture tube shorted the choke according to the voltage of the picture tube. He began to turn on.

All models are on the ICC20 chassis. Fault: a bright vertical bar in the middle of the screen. In a TV with such a malfunction, the following revision is necessary.
  On the PCB side, add the RGP15G diode in parallel with LL010 (cathode to the collector of the TL010 transistor). Replace the inductors LL011, LL012, LL032 and LL030 with jumpers. Remove the resistors RL032 and RL030.

Chassis PLT51A

  40RW34E

29MH50N. Fault: does not exit standby mode: The LED on the front panel flashes 3 times. The transistor of the amplifier of the geometrical distortion correction circuit of the raster TL003 (BD242C) is broken. After replacing the transistor, it punches immediately when turned on. The capacitor at the jumper JL915 turned out to be faulty (leakage; its resistance was about 200 kOhm).

21MH10C. Fault: when turned on, the red LED lights up (standby mode). Then the LED switches to green (operating mode) and after 1-2 s returns to standby mode. The process is repeated. In standby mode, everything is normal, and when you switch to the operating mode, the microcontroller's supply voltage drops (+5 V), as a result of which the TV goes into standby mode, the controller's power is restored, etc. As a result of the analysis of the installation, it becomes clear that the controller power is taken from the power supply in standby mode, and from the line transformer through the 1N4001 diode in operating mode. This diode was broken. While he was going to change, the diode was restored, the TV worked. After replacing it, everything works fine. The owner of the TV reported that he suffered from this defect almost from the very beginning. Sometimes the TV began to work itself, sometimes it was necessary to call the masters, but as a result of the search for a defect, the TV’s performance was restored, and the device worked for several months.

21DG16KR. Fault: does not turn on. The client complained that during the operation of the device, before the final breakdown, a strange noise walked on the image. In the primary circuits of the power supply turned out to be a faulty Zener diode DP27 for 27 V, in the secondary circuits the transistor TP52 (BC546) is in a leak, it is better to replace it with BC639; however, you have to bend your legs, because the pinout does not match. I also recommend replacing the TP50.

21DG16KG. Fault: the raster is flooded with white, reverse lines are visible. Cause: Capacitor leak in the ICUT signal circuit, pos. Designation CV035 (560 pF).

25DX25KG. Fault: the kinescope, when turned on, lights up brightly and turns off, then everything repeats. K.z. +200 V circuit - power supply of the TDA6107Q video amplifier. Zener diode 1.5KE250A is broken. Installed on the tube of the tube.

[email protected]   Thomson ch. TX807C-CS. The problem with the power supply.
   I read all the messages discussing problems with the PSU on this chassis and could not find a solution. The power supply gave out instead of 106 volts 30. All other voltages were also underestimated. Capacitor CP009 3300pF / 1600V in the open.
   Thomson 29MH50N. Does not leave standby mode. The LED on the front panel flashes 3 times. The transistor of the amplifier of the geometrical distortion correction circuit of the raster TL003 (BD242C) is broken. After replacing the transistor, it punches immediately when turned on. The capacitor at the jumper JL915 turned out to be faulty (leakage, its resistance was equal to about 200 kOhm).

Thomson TX807 (TMP47P1637VN processor). Defect: the TV does not exit standby mode, the indicator LED blinks and the modes on the processor are pulsing (pin 20, 33, etc.) Cause: ST24W04 memory chip is faulty.

THOMSON 21DG16KR. Defect - does not turn on. The client complained that during the life of the device in the image there was a strange hindrance. In the primary circuits of the power supply unit, the faulty DP27 zener diode turned out to be 27 volts, in the secondary circuits the TP52 BC546 transistor is in leakage, it is better to replace it with BC639, though you have to bend your legs, because the pinout does not match. I also advise you to replace the IP50.

   THOMSON 14MK10E Chassis TX807CEU, processor TDA9351PS / N1 / 1K0180.THOMSON 14MK10E Fault: when you turn on, you can hear the buzzing of the TV does not turn on. The S2055N line scan transistor failed and naturally the power supply turned out to be overloaded. After replacing this transistor, the TV turned on, but there was a white-gray image on the screen. Silhouettes were barely visible, no graphics. After replacing the TDA9302H frame scan chip, the TV worked fine.
   THOMSON 21MK10E chassis TX807C. Fault: the power supply burned out from a foreign object (10 kopecks). The transistor STP3NB90FP and the resistor RP008 5.1 ohm failed, after replacing the burned-out elements the PSU did not start. With a thorough check of the zener diodes and diodes (zener diodes were checked for stabilization voltage), the evil source DP027 BZX55B27 was detected and replaced (its stabilization voltage became 9 volts instead of 27). The tester zener diode rang as good.
   THOMSON 29DM400 ETC-210 100Hz Failure: for a short period, two devices with the same hole failure in the TDEG OREGA 10829180. For replacement, I used an analog HR80001.
   THOMSON chassis TX807. Fault: the TV does not turn on, the LED blinks once a second. No horizontal scan start. Faulty firmware in the memory chip. After installing a clean memory, the TV turned on! but after 20 sec. it all happened again! To troubleshoot, enter and exit the service! TV works without any additional adjustments!
   THOMSON chassis ICC17. Fault: it does not enter the operating mode, it is broken (BUH516), after replacing the transistor, the body generates an error 27. TDKS OREGA 40351A-5 replacement is required. I installed an analog of HR8846. The phone turned on, but did not set the balance, it smears red. On the kinescope board, the LB02 choke set R (1st) in parallel with it. The balance has been established.
   THOMSON chassis ITC008 Fault: when turned on, high appears and the TV turns off. Protection is triggered due to an open in the correction block of the resistor RL102 3.9kOhm
THOMSON 20 "- TX-807 chassis. Poor contrast, almost unadjustable. The menu is normally contrasted. There is sound. I increased the nominal value to one moment - resistor RL002 (82 Kom) in the OFF circuit.
   Thomson 20MG10C. Defect: the TV does not connect, the standby indicator blinks. All signs of the departure of the firmware. If you press the POWER button on the remote control and hold it a little (for about a minute), then the TV will connect and then function normally.
   Thomson 21MX15KG (processor TDA9554PS / N1 / 1/0683). Defect: when switching programs, the image is not visible for a long time, it displays on the screen - PIN XXXX. After installing a clean memory chip, it was self-initializing. Everything went well, it was not even necessary to adjust the size of the raster.
