Anyone know anything about Dlp Tvs?

Ive got a samsung Hlt5676s Dlp tv that stopped working right. when i hit power it turns itself on and off about 10 times and then all 3 lights on the front flash.

I Have already done the following previously, the last 3 times i fixed it. Replaced bulb, Replaced Ballast. Fixed.

Replaced Bulb with original Phillips lamp because cheap one burned out quick. - Fixed.

Replaced Dmd Chip. Fixed.

Now, Because its turning on and off i just replaced the capacitors on the power supply, But that didnt do anything.

I measured voltage on the wire leading to the ballast and it is 430v. appears to be operating normal and the lamp looks good.

ive also bypassed the safety switch for the back cover just in case it was bad.

These fking things ... passion project if ever there was one...
... the 3rd part of these things is the color wheel afaik? If it's not spinning fast/smooth/regularly enough I think it shuts you down often? Often prevents lamp turning on?

The only other thing will be whatever sensors doing the shutting down - perhaps these are bad - especially what with the turning on/off. Perhaps a heat sensor if not color wheel sensor?

Good luck!

p.s. tried avforums?

I fixed this thing. New ballast, new bulb, and it works again.
