My Samsung LCD TV, Model LN26A450C1D, will not turn on, either with the remote or by the On button on the side panel. The red light remains on at the botton right of the screen. This happened yesterday also, but it eventually turned on and was fine. I already made sure the electrical outlet is ok, and there are new batteries in the remote.
my 42 inch vivtek dlp won't turn on- that's after replacing the bulb and ballast. I get dlp hardware error ( by way of flashing led's). Could it be just that I need to replace the color wheel? No one services this unit in my area.
