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

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

Vizio VT470M no picture, no sound, no backlight. Power supply board looks good all voltages appear correct (24V, 5V, and 3.7V) and no "bulged" capacitors . When I unplug unit for two hours, the screen comes on normally backlight comes back up and picture is normal, but changing the channel causes it to go dead again. Bringing up menu with remote is really sluggish and when attempting factory reset, it goes black. Vizio light on the front of the TV comes on and off when pressing power button,

We have a samsung television that is few years old. All of a sudden we had thick green and purple vertical stripes over the picture and sound was fine. However, playing the xbox or watching a dvd, it looks perfect. I found that when we unplugged the power cord, it would be fine for a while. But now that isn't even helping. Today it seems that the sound went as well! Time for a new one-or simple fix?
