Hi,

Usually the secondary fuse is blown and also check horiz output xistor. stand-by indicator light is blinking continously once a second, no pausing. The possible problem indicated by this type of blinking could be no reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective. How would I go about determining which one of these problems I have if any and then fixing it. Is it at all possible that the convergence panel would need to be replaced.

That would all depend on how much electronic circuit training you have and if you can use a schematic and know how these TV circuits work. You will need a mutimeter and a scope to trace the video. The problem you have is on the M board or the U board, but a good going over, checking voltage will determi this .

Thank You

I got a problem in TV. TV starts and shutdown immediately, while from sound its looks like that raster is going up but no picture, no sound. Red light is blinking. This happens only when i power off the tv...


Hi Sikandar,
Let me know how many times red led blinks as there would be an interval of 3 seconds so count blinks from pause to pause.
Is it Sony AR25M61 model or any other?
Above info will help to diagnose problem.
Thanks.

Sony 50 Wega LCD flashing red light


Hi

How many times is the red light flashing? The number of times the red led blinks means---


  • 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.
  • No blinks(Unit is dead) - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
Please do rate this solution as FixYa and revert for further assistance.

Thanks

Kdf-60xs955 red continous blinking lamp light


It's in standby mode.

Do a reset and see what happens

While holding down the reset button on the remote
Press the power button on the tv
(The tv will turn itself off the back on)
Now release the reset button

It sounds like the lamp needs replaced.


Please rate this a fixya
