I am repairing a sony TV KV-32FQ70E. The led blinks 5 times, stops and blinks again. Please tel me what means.


  • 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, (G2 voltage).

Check the tube emmision, it may be too low to track, causing that error.

Hope that helps

Sony Bravia KDL-52XBR9 wont turn back on red led flashes unless I uplug and plug back in. Did firmware upgrade to newest aa0143pn, still happening.


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

  • One blink - not used for the self-diagnosis

Sony KV - 36XBR400 36" keeps going to standby - blinks red x5


5 blinks is an IK balance problem. it means your picture tube is not drawing the correct current on 1 of the 3 cathodes (IK). there is a good chance the tube is bad. if you reported it while under warranty you should call the warranty company and pursue it.

Picture and sound cuts off ,greem stb light keeps blinking TV turns on after 30 secs shuts off after 30 secs comes back on. Continious loop


How many blinks do you get? Depending on the amount of blinks you can figure out what the issue is.

If it blinks 6 times you can get the fix at

No power RED Standby LED flashes 6 times/KDF55XS955, KDF60XS955, KDFE55A20, KDFE60A20

They have other fixes for E60A20

WONT TURN ON


If you know how to trouble shoot solid state electronics and know how the curcuits work, then Im sure you can handle this repair. But my friend a tv set is not a place for a handy man to be experimenting around inside of, as there is alot of high voltage inside this set even when its turned off! Its best if you do not know all of the safty issues to seek out a pro to assist you in this repair. It could be a bad solder connection, or a bad filter capacitor that supplys the B+ to the video chip. Without looking at a schematic and tracing the circuit, its all a guess. There are no real user replacable parts inside this set. Good Luck PS please do not forget to rate this thread.
