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. Could you possibly help
Hi. This is an all too often occurrence. The TV's manufactured in the earlt to mid 1990s relied on an inferior set of capacitors in the power supply and mainboard components. They should have lasted about 25 to 30 years, but most are on ...

Toshiba 40rv525rz shut off while playing xbox. When it shut off i could see a small white line on screen then went black. Tryed to unplug it for 5 minutes and would not turn back on. All it was doing was flashing the lit toshiba emblem up and nothing else! Talked to a couple of people and they told me it sounds like a power supply problem! So opened up the tv and saw that the power supply had a burnt resistor and there was also sut on the backlight inverter so i ordered a new power supply and in

I have a mistubishi WD-Y57. I replace lamp 7 month ago, and now my tv doesn't work. I have sound but no picture. I took off the plastic grill from the back of the tv to see what it was doing when I tried to power it on. I see the fan turn on and see the light trying to cut on. It flickers light. It try two times before shutting down. If I see light flicking, does that mean the lamp isn't the problem? I tried to read the code light by holding those two buttons in front of 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

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.If you ...

Westinghouse LD-4680 Turn TV on this morning, heard the normal click sound of it turning on, saw red LED glow coming through bottom grill - like normal....then about 5 seconds later, heard another click, and red LED glow turned off(TV turned off). That was using remote.
Tried turning it on with power button on TV itself, heard the click when it turns on, and just as fast, heard click indicating it turning off.
Now, it does absolutely nothing - acts as if it is not receiving electricity.

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.

I recently purchased a used Pioneer Pro150FD and was told it worked. Now that I have plugged it in, I get a clicking that the power is on, but there is nothing coming on the screen. I also see a small red light illuminating from within (through the back panel) when the power is switched on.
I am using a "osiris" remote that came with it and the control says "PIONR" but the switch doesno't work. I have installed new batteries in the remote.
