The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

The technician was correct.

This problem is generally considered to not be economically feasible to repair. Your best bet would be to shop for a new TV.

The capitors on the back might be bad this I have fixed on these tv's many times. That could be one of the problems and the capitors are on the power board inside the tv. If you do not know how to work on electronics I would have a pro do it they contain hight voltage so be careful if you try to fix it yourself.thanks

When i turn my samsung 40 inch tv on it makes a tick tock noise and takes a very long time to come on


To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

Samsung 40" tv won't turn on


i had the same problem, you'll have to call the samsung service center. You TV's part which looks after the voltage connectivity has failed. This majorly happens due to voltage fluctuations. The part will cost around Rs. 2800 and service charges will be applied by the company.

You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.
