Turned itself off. I turned it back on and the green power light blinks for awhile then blinks red for awhile.no picture or sound


Get rid of this TV. Had one and replaced the bulb and light engine many times. Just buy a Samsung or Vizio 50+ inch instead and be very happy. Those Panasonic projection TV's were terrible. You will find a 50 inch Vizio for around $500 bucks and it will blow your mind how great the picture looks.

TV turns red,shuts off, stand-by light blinking 8Times


Eight 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.

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.

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.

While it is suspicious happening so soon after lamp replacement, your main power supply may have failed. In earlier sets, these were problems that eventually happened.

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

Red blinking light


It's most likely convergence -- the small board up and to the right inside the back of the TV, which has two large amp Ic's attached to it..
Unplug the +/- 20v line on the fron left corner of that board (red in color) and then try and power on the set... If the set comes on the board needs to be repaired and it's an easy unplug and two screws that mount it inside.

Rca 52" problem


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
