I had similar issue with power light blinking 3 times and no audio/video.

The problem was a burnt resistor and gone convergence ICs. I replaced both ICs (safer bet unless you know exactly which IC covers what guns in your specific TV) and the burnt resistor by myself and the TV looks good as new.

My sony rear projection tv screen went red on all modes like video and such sit for a bit but the red is still there when it is turned on wtf???


Sony TVs has an Optical Block issue. If there is such an issue with the TV, then picture on the TV will be in red/blue/green tint. Try resetting the TV to the factory settings and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then the TV requires service. I suggest that you contact the Customer relations team and check for the available options. As Sony provided free service in the past for such issues.

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Did you check or change any of the resistors - Check in the area near the STK IC's for burnt resistors.

I had this problem and at the same time I was getting blue tint. When the blue got darker, this would happen, Adjusted the voltage on the guns (3 screws in the front - lower panel off) and the blue went away and it stopped turning off. But later, it would start all over again. Same procedure, same fix.
