Hi, although its a DLP, having a upward rolling picture (just like an old tubes TVs) with blue screen two seconds later and window massage "not supported mode" or "no signal or weak signal". Cleaned it behind, but still does it. At first, it was on very seldom and very few channels, but know on all of them. Lamp is fairly new. ANY CLUE ANYONE!!!!!!!!!?? Thanx
Samsung knows there is a failure history with these "N" model boards. Call 1-800-SAMSUNG prompts 2, 1, 3, 1 and be very persistent. Get past the first levels. You wouldn't be the first person out of warranty to be offered a newer model for the cost of shipping. Good luck!
