If you are saying the picture comes on red and then the tv turns off?
I would suspect the video ic on the red picture tube pc board has shorted out.
This is a pretty common problem

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.

Red/green lights both blink and tv will on turn on


Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats...


  • 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 A2 slightly.

Projector screen turns off after 10-20 seconds


Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

When turning on the TV the green light on the front does not come on. You hear a click and then about ten seconds later you hear another click but the tv never comes on.


What light do you get, green blinking, red blinking, yellow steady light or yellow blinking light. The led lights will tell what is wrong with your tv.
