Resolved Question:

My Sony Wega TV started turning off by itself. When it does the timer light is blinking on and off. I checked the sleep timer but it is off. I does not do that all day only latter at night. What could be wrong?

Thanks for model info.

Please count how many times standby / timer light is blinking after long pause, this is an error code.

it blinks 3 time than pause then 3 more and so on

OK, 3 times red blinking light shows problem of Over Voltage in power supply section that is located on DZ board.

Do you want to repair TV yourself or need to know DZ board cost to have an idea about repair cost?
