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

SOURCE: sony bravia kdl 32l4000 - color bars running vertically on screen

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

How do you turn off TV?


Press the Power button on the remote control once, when the set it powered up. It will power OFF. If you want to power down totally, just switch off the main power at its panel.

Sony bravia lcd won't power on after lightning strike


I am sure the tv is shot from the surge but you can check a few things. I would take the tv apart and test the power supply first. Look for obvious burn damage throughout the boards. If there is a blackened one (prob video board) then you can try to replace that. Don't worry about taking this apart and breaking it further. In this case it can only get better for you.
