Negative image? (Samsung LN40A550)

[qanda]This thread is about the Samsung LN40A550. Click here to see full specs[/qanda]For the fourth time in 3 months, my new Samsung LCD - LN40A550 (HDTV) - went from a nice color picture to a “color negative image”.

The problem is fixed when I turn it off. Any idea of what’s going wrong?

Pictures of a similar case can be found here.

There have been several reports that replacing the DMD board will solve this issue. I don’t know if replacing it will actually fix your problem. The board price is around $650.00 U.S. and up.

When did you purchase the T.V.?

Have you tried contacting Samsung about your issue?

Have you tried contacting a authorized repair shop about cost?


Hi “platinumsword”, thanks for your reply.

I purchased the TV in January 2009.

And no, I didn’t contact Samsung, neither an authorized repair shop.
I´ll do it today.
