Question about Sony FD Trinitron WEGA KV-32FS120 32" TV

1 Answer

Sony 32fs120 I think my board blew. The tv fell and a piece of the board broke off. I tried fixing it by jumping the circuits. When pluging in the mains it goes into protetion mode. I checked continuity and it seems fine. I tried to get a diagram but witout success. here in South Africa you do not get other boards that will fit, and to import one will cost too much then I can just as well buy a new tv and will sadly would have to let the sony go Can you please help? Johan Sorry for the bad english

If this is indeed a Sony KV32FS120 then I would bet your CRT'S shadow mask is warped severley as well which will cause many rainbows in the picture once the set is up and running. Count the loss and replace the set.

My tv fell and I think the sensor is ruined. The remote now won't work. The plastic isn't broke, but I think sensor is broke as the tv fell on it's face.


most of the time, the circuit board cracks around the remote sensor, when there is a fall like this. the TV will have to be taken apart to check this. Do you have that capability?

Here are the Sony blink codes. I would download the service manual for your set from one of the sites that advertise here to verify this. If a vertical circuit failure is correct, that is a very affordable fix at any repair shop.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).
Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.
