This problem is common in Samsung projection TVs. The DMD board is going bad.

Go to Samsung.com for solution. There is a switch that just needs to be repositioned behind access door on rear. Fixed my HL-S5086W ok.

I suspect the lamp is failing on your TV. The lamp replacement code is listed on the side of the TV on a sticker that is orange and white. It will start with BP96-. The lamp code is crucial on these older Samsung DLP's because they used quite a few different styles. Please take a few moments to rate my answer. Thank you...
