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 only lasting 5 or 6. The cheap capacitors pop, like a small balloon, or an overheated radiator, the capacitors contain an electrolyte gel, and this gel swells when induced with a charge. The cheap capacitors can split down the sides, boil over, or even pop the top off of them. If you look at the circuitry, you will see them standing up like small buttons, most with 3 wires coming out of the bouuton of them. Look to see if they have exploded like a battery, if, not, then your entire power supply is likely at fault.

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

I have a Sony Bravia KDL-40S4100. I turn it on and I can hear the solenoid click, the green light is on and I get a faint blue illumination. I do not get a picture or sound... or any response from the remote except for on/off. I tried unplugging it until I heard a click (I assume all the caps were discharged at this time) and tried again, still nothing but a green light and faint illumination. Any idea what I am dealing with... besides frustration?

My LC-37SH20U was working fine. Then, when I gor home from work and turned it on, I heard the usual volume and the "click" from inside, then the picture comes on. After only 4-6 seconds, the screen went black but the volume stayed for about 3 seconds. Then I hear a click again, and evrything goes off, but the power indicator keeps flashing green.
When I hit the power button both on the set or on the remote, nothing happens.

This is a fault solution which can be checked and corrected by you assuming that there is no component failure. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering ...

Our RCA 27 inch TV (F27227EM), purchased on 1992, is hooked up to our DirecTV DVR Plus box. A simple click of the "ON" button on the DirecTV remote has always turned on both the DirecTV box and the television simultaneously. Yesterday, the TV stopped coming on even though the DirecTV box still powers up. No sound or picture on the TV. If I get my ear close to the TV I can hear a very faint click as though it is trying to turn on, followed a few seconds later by the same faint click as if it'

Unplugged for 1 hour, plugged back in again, nothing, uplugged over night, plugged it in, still nothing. Tried other outlets. Checked the safety fuse, it is good.

Vpw 425 viewsonic, have owned this Plasma, for several years, has always operated fine. Today it won't turn on. Main power switch is on. Standby switch is red. When I push the standby power button, it changes from red to green, I hear a click, then within 2-3 seconds the standby light turns back to red. I removed the back panel and tried to start again, after several tries there is a red indicator light (inside the panel) labeled "main power" that comes on and stays on.

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.

My Toshiba Regza AV55 has stopped working completely. After turning it on at the mains there was no power to the tv, i've tried it in various power points and even changed the fuse but there is still not power, no red standby light, nothing.

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

My LG 52sz8r tv wont turn on. It suddenly stopped working. I presumed the bulb needed replacing as the bulb light was on before it stopped working, but did not come back on. however after replacing the bulb the problem remains. After pressing the power button the red standby light comes on, but when i try to operate the tv the standby light turns green and blinks about every second and nothing happens. I can hear a small click in the unit a few seconds after trying to turn it on. any suggestions

I have a Mitsubishi WS-55909 projection TV. There was a power outage and when the power came back on, the TV won.t turn back on again. There is this light (Timer) that keeps on blinking on the front panel of the TV. I tried unplugging the Unit and waited for about 15 to 20 minutes before turning it back on , still won't work.

I have a Polaroid 2611-TLXB TV that was manufactured in September 2007 and recently, I turned it on one night and there was no screen at all. The blue power light was on though and I could turn it on and off with the remote but still no screen. I tried unplugging it and plugging it back in but nothing changed. I checked the back and there is a red blinking light.

Samsung ln32c450. Previously: Turning itself off/on, a.k.a "power cycling".
Now: tries to come on but only a brief momentary white flash on the screen, then nothing. Remote detector circuit seems to be working fine and +5vsbp seems to be working.
Are you getting backlights but black screen? You need to find out if you are getting PSON (on signal (3.3~5vdc) from main board to turn on the 24vdc power supply for the inverter board), you also need to find out if the inverter board is also getting ...

One simple solution may be to replace the power cable or the power strip that the TV is plugged in to. If you cannot get any power to the TV even after this step, it is most likely a motherboard or some sort of circuitry issue. Make sure you are usin ...
