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! All of the voltages coming off the new PSU are right where they should be, including the 24VDC to the

I have a 2003, KF60WE610 60inch TV. My TV started occasionally losing the picture. The TV will go from normal picture to color patterns yellow/orange, green/blue, black and white. Then I'll have a black screen. The sound is fine. The picture returns without doing anything. The lamp light does NOT blink. The lamp was replaced a year ago. The green power light is steady. What could be the issue?

I recently got home from festival and powered on my TV only to find that the picture was all white(ish). When I say "ish" it's because it was white but with some light blue/grey shades, kinda like a negative picture but with no dark colors. I have checked that the issue is not with the input as I get it from my PC and my PS3 aswell.. When I change input the screen used to go all black, now its light grey, almost white. I tried disconnecting the power over night and check again the next day. At f
Take a look for bad capacitors, but it's much more likely that there's a cold solder joint somewhere.I'd start with the power supply circuit (be careful, discharge all large caps first) and just retouchup all the solder connections on the large ...

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?
Samdavismd,\012 \012It could be either but more than likely from what you describe it is the board which supplies the signal to the light engine. The board in question should have the part number marked on it. See my tip at \012 ...

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. The slave inverter was making a squeeling noise and i replaced it like 2 months ago.

My Sharp Aquos turned off by itself and doesn't want to turn on. Both power and OPC lights blink green.I tried to reset my tv by holding power button and also down volume and up channel buttons. I only got the power light on but the screen was still black. I read that screen with letter 'k' should come out, but didn't. How to fix it?
That procedure was for a full reboot, not the case here. The blinking signals a hardware defect - if it's continuous it signals that the power source has been shut down in emergency mode because another part inside the tv has failed and now it acts a ...
