Customer Question
When I turn on...

When I turn on TV, it tries to start and then turns off and then tries to start and then turns of ad then turns on and then turns off, .........I think it is the power board?

Technician's Assistant: What's the brand and model number of your TV? How old is it?

Samsung, Model LN40A750R1F, 2008

Technician's Assistant: Does the TV menu work? Do you have the same problem on all sources/inputs?

THE SCREEN NEVER COMES ON. IT IS JUST RECYCLING?

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

NO, ONLY THAT "I" THINK THAT IT IS THE POWER BOARD?

Mostly it is the power supply board problem due to the failure of capacitors on it and sometimes the mainboard also can be a cause of the same symptoms but most of the time it is power supply board problem

Please click the following link to view power supply board OR a repair kit info if you're looking to attempt to repair the TV yourself
