Your DMD board is now misaligned. It can happen when you changed the color wheel. All you have to do is pull up on your DMD board. I would use both hands, one on each corner of the DMD board and just a little at a time until you get it the way you want it. If you have a space at the top, then just push the DMD board down the same way.

Im getting a whirring noise in the back of the tv but the picture and sound is still on. picture quality is still good. i dont know if its the fan. color wheel was replaced a year ago. but the tv stopped...


Well that whirring noise is most probable to be the color wheel. Funny thing you replaced it a year ago. But it's most probable that is the issue. You did get the right one, did you? Because with Samsung TVs they have 2 types of color wheels, either gold or silver bearing.

Samsung DLP HL-R4266W..no sound or picture. TV is completely dead


Assuming the noise is a high-pitched whine, then yes, it is the color wheel.  If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync.  The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.
