I have a Samsung LN40A550P3FXZA that is giving me problems. When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

This is about the PN50A450. Last night the television started making a loud buzzing noise, the picture turned into red fuzz as well. I turned the television off (buzzing stopped) and back on, with the buzzing returning but without any picture now. It is not obstructing the sound coming from the surround sound speakers, but instead coming from the TV itself. In fact, the buzzing stops when the TV makes its start up noise and then starts again. The TV has been unplugged in every way but the proble

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

Hi, can you help me with this TV please.
Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on. I replaced the power supply board and now my TV turns on and the screen lights up but I get no picture or sound. The slave backlight inverter board has a blue light when you turn the TV on but goes away shortly after. The screen stays on but I have no sound or can't control the channel, volume or source button. Please help.
If the tv is not coming on but there is no picture or sound then it is a 100% guarantee that its a problem with the audio/video main board of the tv. I am sure that replacing the same would resolve the problem. Please get me the part number that is p ...

When I turned on TV after about 1 week of not using it, it took a long time to start up. Then, I noticed a flickering in the picture. I checked all the Picture settings and noticed that I must turn Backlight all the way off or on lowest setting 1 to stop the flickering. The higher the Backlight setting, the faster the flickering becomes. However, the picture is too dark on Backlight Off or 1 and increasing Brightness to 100 does not solve the problem.
