Having problems with your Flat Panel Televisions ?

Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound. The Red LED on the front flashes when it clicks but nothing ever appears on the screen. I removed the back of the TV and inspected Capacitors but do not see any that look to be bulging. When I try to power it on with the back off, I see a green light quickly flash on a logic board just below the power supply board. Are these clues helpful

TV has worked just great since purchased in 04. Sat down this morning, grabbed the remote and nothing happened. I replaced the batteries in the remote, tried it again and nothing. I tried the manual power button on the front of the TV and still nothing. I tested the power outlet and it works fine. As I plug the TV in, I hear a soft click as if it is trying to power on but still nothing happens. I pushed the reset and it makes a soft click but still no picture or sound.

Lg 42lh30 Tv runs well for awhile 20 minutes to an hour, then a click sound comes out of just the right speaker. Then the TV freezes and none of the buttons work on the TV. Once I cycle the main power switch the tv will not turn back on, thought a red light shows that power is available. I did some minor troubleshooting and found when I disconnect the T-Con from the main board, I do not ever get the clicking sound, my buttons always remain functional, and the TV seems to run fine (I can hear the

My Samsung Plasma 42 in. TV turns itself off after a couple of minutes of being on and then makes a clicking sound like its trying to turn on again but it doesn't turn back on. It just makes this clicking sound. If I unplug it, sometimes it will function normally again and sometimes the same problem occurs. We thought it might be the power strip so we plugged it into a different outlet. At first, this seemed to work. Then, the cable box and the sound system started turning off spontaneously

I have a Sharp LS-26SB24U that has a white screen when turned on. I tested main fuse and F404 fuse both were good. I tested power going from F404 to ground and it was 13v on both sides. I guess my next step is to see if the T-con board is getting power but I'm not sure how. I tried following a white line that said power and along is was a hole and I went from there to ground but got nothing. Any help would be greatly appreciated.
