Re: samsung ln46a540p2fxza no power

You've abandoned at least two repairs in your last posts. We like to actually fix stuff, not waste time. It's very frustrating when no reply come back.

How about some pictures? You've been here how long, and no pictures? No list of what you've tested already? Have you owned the set since new or ...?

Leave the TV unplugged, disconnect the large cable between the Main board and the power supply board, plug the TV in, the backlights should come on right away.
What is the P/N on the power supply-inverter board? BN44-???????

Re: samsung ln46a540p2fxza no power

You have power supply/inverter board combo, the two boards on the side are balancer boards with lamp current sensing transformers for each lamp. To verify if you have power supply-inverter board problem or the main board problem, you have to disconnect the cable as I suggested in post 6, if it does not stay on, then you have power supply-inverter board or one of the lamp draws too much current, you must follow my suggestion on post 6.

Re: samsung ln46a540p2fxza no power

I unnpluged it and get no power at all

Re: samsung ln46a540p2fxza no power

If the backligts do not turn on the minute you plug the TV to the outlet with the large cable between the main and the power supply board disconnected, then you have bad power supply-inverter board or lamp over current problem.

Thanks to TOM66, he has the diagram for the board.
And this is how to test to find out if the lamp is bad.
