SOURCE: My Sony Bravia KDL-26S3000 won't turn on and is stuck in standby.

Hi,

There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.

Thanks

There is a error in TV.Count how many times blinking the red light.

  • 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 GA_googleFillSlot("TL-IMU-Article"); 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. GA_googleCreateDomIframe('google_ads_div_TL-IMU-Article' ,'TL-IMU-Article');

  • 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" boards

i have the same problem, apparently the LCD panel needs to be replaced and this will cost more than the tv is worth... Advice is to not buy a sony again, because this is a common problem and they wont extend the warranty, even if its 2 weeks after it runs out...

Sony Bravia KDL-55nx720 My tv is stuck in standby mode. Blinking twice.. Would replacing the power supply possibly fix this problem? Please help.


Normally yes. Blinking twice is power protection trip. Look first for open resistor, broken fuses (and short circuits or broken transistors / ICS if thats the case).

The fault is with its main power supply regulator section itself. One or more voltage rail is missing. Your TV need a through checkup. Seek tech assistance.

We lose audio on our Sony BRAVIA KDL-52W4100


This problem appears to be an issue with numerous Sony Bravia owners of the same model. Although still seeking a soulution, it would appear that our cable provider (Verizon) has replaced all of their components and the Geek Squad from Best Buy where we purchased the unit, points the finger at Verizon. None of our other Fios-equipped TV's exhibit this problem so I am glad we bought the service plan with the TV and will continue to seek a remedy.
