This question comes from Laura...

First, I want to thank you for the great instructions on how to buy and replace our color wheel. We installed it in May and it worked like a charm.

You're very welcome!

But I'm afraid your luck is running out...

Now, we have horizontal lines on the Samsung 43" DLP and we are wondering what it would take to do it ourselves. Any luck with these problems?

Unfortunately, I'm afraid this is very likely a faulty DMD board, which is essentially a computer board that the brains inside your television. It's an expensive thing to replace. You can get refurbished boards for a few hundred dollars. New ones cost several hundreds of dollars.

While it is very possible to replace it yourself, most people opt to cut bait at this point and just shop for a new television.

I've got a Samsung DLP in my basement that was given to me and is waiting for me to test out the procedure on, but I can't bring myself to spend the money. Someday...
