Re: New Members - please post your introductions here

I'm logging in for the first time. I'm working on a Samsung-ln40b500p3fxza 40" that is not powering up. I replaced two defective MOSFETs on the PS board Bn44-00264A with no improvement. Is this a plasma tv? I have never worked on one before. My experience is led on TVs. Any suggestions are welcome.
