    Hello Cailloux,

    Your solution worked for me. My Dav-C770 system was doing as many of the others reported here - stuck on standby. The capacitor at C914 was 47uf-35v, as opposed to the 50v that is on your system. I found a 47uf-35v at Radio Shack for under $2.00. After a couple of wire snips and a "not so pretty" soldering job, my Dream System is back up and running!

    How did you know that this particular capacitor was the problem?

    Great way to start the new year!

    Thanks!!!!!!

I had the same problem, red blinking light after owning for several years. I decided to replace the capacitor at C914 to see if it would work, and it did. Apparently that capacitor is prone to failure. Since this seems to be a common problem, I created a web page detailing the repair. Hope it is helpful. Repair cost $1.39 + tax.

This worked like a charm. However, my display is still not working--ie you have no idea if you are on dvd function, tv1, tv2, etc... Anyone have this problem and if so, is there a fix?
Thanks,

Your unit has DC Offset(a damaged amplifier) which is why it keeps shutting down. If you are interested in repairing your Sony, please visit my website at audioserviceclinic.com. Thank you.

I have sony Bravia KLV -32V300A suddenly shut-off while I am watching power indicator went off and standby red light blinking 5 times then after 2 seconds off then red light blinks again 5 times and so...


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.

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
