No luck with the component video or the "hack" composite input. There's no indication of any output to the TV. I also tried just the yellow video composite output (both of them) to the TV composite input and there's nothing there, either.

Re: New Members - please post your introductions here

Hello all,

I just registered on this forum - mainly trying to find information on my Samsung HL-P5063W dlp TV. I'll search the archives first, but I may be back to ask about the ballast and how to tell whether it's good or bad. I've changed the light bulb, but now the TV turns on for a few seconds and then goes black. I can get it to come back but only for 10-20 seconds. Anyway, I'll search the archives first. Thanks for the great site!
