So my TV turns on, and it works perfectly for about ten minutes. Sound and video is fine. Then it starts to flicker and shuts down. Replaced the lamp and color wheel, any other suggestions?

8/25/07 Coincidentally, I have just run into the same problem. I spoke with Technical Service at Samsung yesterday and after 15 minutes on the phone they couldn't tell me what was causing it. I then did numerous web searches and came across a sight where technical experts discuss problems. Turns out it may be a problem with the Digital board, the A/V Board or the DMD board. Cost for repair (depending on which board it is) will run $400 - $1,000 or more. Repair man is coming out Monday to diagnose the set.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast is the most common failure besides the lamp.The ballast is the one that displays the lamp indicator if it's not able to power bulb or if bulb is not responding.Have a blessed one!

I would suggest a simple way to know if color wheel or not; usually color wheel makes high pitched whine or even a grinding sound (like a bad fan).

If you remove the lamp and look carefully where it faces the color wheel is there; you are looking to see if it is shattered or missing pieces etc.

What happens is if the wheel shattered or even slowed way down the set will detect this and shut down. The bearings in the tiny motor for the wheel lock up etc as it is turning at over 12,000 rpm.

If you find it is shattered they are available on the net with video instructions for most models; there are a few things to be aware of that are not usually mentioned when you buy a new wheel and I if you go that route I can tell you a few common pitfalls to avoid.

If you have questions or need assistance let me know, I am here to help.
