I have a Sony Bravia KDL52W5100. When I turn on the tv sometimes everything is fine but other times there is no pic only rainbow stripes. I have to turn off and on the tv several times or unplug the tv to get a picture. I have tried rebooting the entire system it worked fine for couple of hours then the problem came back. Sometimes while I am watching a show the screen will gradually change into the rainbow stripe. Do I need to replace my screen and is it worth it?

Have Protron PLTV-3250 TV and I was told the power supply board was bad. All indications concluded this was the problem. Replaced the power supply board (FSP194-3F01 power supply) and turned the TV on. It has power, but I have no picture. I can hear the sound from each channel, but that is it.

I just purchased my Mitsubishi WD52628 projection television used as it only needed the bulb replaced. I replaced the bulb, however now it will only run for a couple of minutes then the remote and all selection buttons will freeze up and it turns itself off. After turning itself off, the green timer light flashes rapidly. Once it has stopped flashing, I can turn it on again only the problem is the same. I have tried the reset button on the front, no change. Any suggestions?

I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light.
When I turn on the TV, green led comes on, then after about 30 seconds red led blinks once, then green resumes. The green led stays solid. I think that's a SONY error code, I tried to look it up but can't find anything useful.
I have replaced the power supply, AU board, backlight inverter, logical board, and the second power supply board.
Any suggestions? I haven't checked the t-con bo
