5 time blinking Sony Trinitron (Flat Panel) tv


  1. 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.

TV won't turn on. flashes a series of 5 red lights instead of turning green


Usually Sony and LG Blinking Codes are the same. Here is what I have.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  • 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,
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  • 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. 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.
  • 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.
  • Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing 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.

Tv shut off in the middle of a movie now power light on front just blinks red and does not respond to the remote


Count the number of time the light blinks and if there is a sequence. Google your make and model number and add "blink codes" to the end. The blink code of the red light will tell you what's wrong with your tv. It's a self-diagnostic event.

Started blinking and the red light blinking now and no tv screen when i turn on just blinking red power light


The blinking light is a self-test diagnostic. If you can tell me how many times it blinks in between each pause and what is the make/model of the tv, I can tell you whats the source of the problem.

TV shut off while watching and won't come back on


It seems this is a self diagnostic function. the official sony codes are as follows

  • 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.
It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps

I have a sony wega


Generally speaking whent he set shuts itself down, the standby light will blink a code. This will be a count followed by a short pause and then the count again etc.

When teh set shuts down, count the blinks and post it here. That will indicate the circuit that has the problem.
