The picture will come on when you first turn it on but after 15 minutes or so it fades away. The sound still comes out but no picture. Sometimes it will come back on on its own after a while and then go out again. If you turn it back off for 15 minutes or so it usually comes back on. We already bought a new tv and that one works fine so its not the cable box but I would like to put the old tv in my room.

Phillips 409fl7505d/f7 Tv turns on, the blue phillips screen does not come up. It produces the sound but no picture. then after about 10 seconds the tv turns off, This repeats on and on and on until you unplug it or turn it off. I removed the back of the tv toi check the capacitors because that sounds like the usual culprit but they all look fine no expanded capacitors. Any ideas where else to look?

When I turn my TV on it will turn off by itself in about a minute and the red power light on the front of the TV will blink. The remote control nor the power button on the front of the TV will turn it back on. I have to unplug the TV for a few seconds and plug it back in to make it come on. It usually takes two or more of these unplug and plug back in sessions to get it to stay on. Some times it takes up to fifteen before it will stay on. Please help.
This is what 's happening: you give the command to start the tv so the power source is initiated and starts to deliver power to the rest of the components of the tv; one of these components has aged and it requires much more current than normal to st ...

I have a JVC HD-ILA HD-61Z575. The color engine was replaced under warranty a few years ago. Recently, I started noticing some color artifacts in the picture... basically in a dark picture, you can notice red, green, or yellow stars randomly on the screen. If I turn the TV off and back on, they usually go away and don't come back until the set has been off for a while.
I tried cleaning out the bulb area and that didn't affect the issue. I've also yet to have to replace the bulb in the tv,
I only have bad news for you. This tv uses an engine assembly. It is impossible to replace the color wheel only. The entire assembly is quite expensive and wouldn't be worth replacing for a tv of that age. (By expensive, I mean roughly $400-$600, bef ...

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.

Sometimes it will come back by itself, and sometimes a light smack to the side of the set will bring it back. When it's working, picture is excellent. Is it worth spending $ to fix?
