HLP5063 with no picture

[SeanDiddy]

I see a lot of posts on here about no picture with Samsung DLPs. Here is my problem. TV will picture will shut off after about 20 min from a cold start and faster if it is already warmed up, the sound stays on. This is in all inputs including HDMI and coax. I replaced the lamp, did not fix the problem. I took out the color wheel to inspect it. It looks fine and does not make any noise when you spin it by hand. The fans all seem to run fine when the set is on. Any suggestions?

Good luck Sean, I have almost the exact same problem with my Samsung in a post three below yours which I posted a week ago....and no one replied.

I have searched the internet for any kinds of answers, and the best one I found was this one....

They say it is probably the ballast or the power supply.

But then again, I have read other stuff that it could be DMD board, digital board, or even replace your entire light engine. This is a common problem with Samsung DLP but no one has a clue how to fix it?
I don't know what to do?
