I have an HLP-6163WX/XAA with a few problems. The set has a new bulb, ballast and color wheel that all work fine, until it doesn't. The TV will start normally and run with a great picture and all normal. When it runs for 20 -40 minutes the picture will start to look scrambled and will correct sometimes but often it will not. When it happens the tv doesn't respond to the remote and none of the controls on the set work. I disconnect power, let it cool down, reconnect and the same scenario repeats. So I cleaned the whole back out of dust and verified both fans are running well. I then hooked up an additional fan, larger, behind the DLP chip heat sink and it worked for many months. BUT now the TV is randomly going black, the sound still works, the bulb is still lit and the controls still work.
Does any one think it is anything other than the DMD board? The DMD board for this set is BP96-00678B, not availible anywhere, but I find a substitute of BP96-00678F. Does any one have experience with this board as a substitute?
Also, Discount Merchants has light engines for HLP5063W sets for great prices, will these fit the 6163? The Samsung service manual shows only one light engine for the whole HLP range (4663,5063,5663,6163). I would replace the whole thing if it would fit. Any help would be great.
