    I am an electronics technician, but hardly ever worked with projection TVs, so you can talk technical terms.
    My Sony Wega 52 inches, LCD TV, turns on and off in intervals of about one minute two times and then stays off. The red LED blinks, I have not paid attention if any pattern in the red LED blinking. If any, does that mean any diagnostics code?
    Where do I get the meaning of the codes?

The key to resolving this is the flashing standby light. You should see it flash a repeated pattern of X blinks, Can you post that count please? That will indicate the internal circuit in which a problem was found. Armed with that info, we can then suggest repair solutions.

Thanks,
Dan

The blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

Sony wega 55 inch tv turns on fine but after one minute tv shuts itself off and comes back on 40 seconds later by itself and this cycle continues - none of the error code lights blink


This kind of problem occurs when lamp becomes weak that means near to end of working life hours but still not dead nor broken.
Replacement of lamp in tv will solve your problem, lamp replacement procedure is easy and would be written in user manual.
Thanks.

Lamp flashing light on 52 inch Wega


You have a bad lamp. Order a new one (an original Sony, not the crappy aftermarket replacements) and follow the instructions in your owners manul for replacing the lamp.
