Hello! I'm having the infamous black screen issue with my Viewsonic N3252W. I initially replaced the Power supply, because that looked like it was "the fix" for this particular issue. I powered it on, and I was getting the same problem. There was a faint picture (you need to look at the screen from a certain angle, with an appropriate amount of light shining on the screen.) with no back light!

I have a Samsung HL-R5087W 50-inch DLP HDTV and half the screen on the right turns black while watching. I have to power the tv down and on again. The full screen returns but turns black within a few minutes. Is this possible a light engine or digital board issue?

Vizio GV47L...when i turn on the tv, the screen stays black. The vizio light turns white and it makes the click noise like normal but after a minute of it doing nothing the light turns back to amber. I can turn it on and off using my remote. I read other problems where people had to unplug there tv to turn it off. Mine will turn off. Would the problem be the power supply or the motherboard.
