I have an AOC LCD tv when I hit the power button the light turns blue and then right back to orange, at first it would eventually come on after pressing the power button several dozen times and work fine until it was turned off, now it just goes from orange to blue and back to orange or the light goes out completely. I saw a video that said when it does that it could be the power supply or the main av board, what do you think?

My Hitachi Mod # 50FX19K, Ser # V6H000056 Man Aug 1996 has a power problem. About a month ago it started turning off for no apparent reason after I was watching for an hour or so. I could turn it back on with no problem. That time period kept getting shorter and sometimes it would take 2 or 3 tries to get it to come on. Once back on it would play until I turned it off. Now it only stays on for about 30 seconds and I can't get it to restart. If I wait and hour or two it will come back on but only

I have a Sony Wega KDF-E55A20 rear projection LCD TV. The screen stays black when pressing the Power On button. When the Power on button is pressed, a GREEN blinking light (5th light in a row of 5) comes on and blinks about 58 times, along with an intermittent "popping static" noise. It then goes to a STEADY RED accompanied by the 2nd light in the row of 5, BLINKING RED. It continues like this until I unplug the power cord. It will do the same thing if I plug it back in an press the Power On but

Power Surge After house power went out and came on 20 seconds later, my Pioneer would not power back up. It has two LEDs - the blue "on" LED flashes 12 times on, pauses, and repeats the sequence over and over. I tried powering down from the switch and even removing AC power entirely for a couple minutes. The best it would do is to go thru it's normal power up sequence, show a "starting up - please wait" screen for a couple minutes, and then shutting back down with the blue LED flashing.

RCA D52W19 52" Rear Projection Television
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 9 yr old D52W20 RCA tv. It turns on and is fine for about 35 minutes. Then it turns off and then right back on again. it takes about 15 seconds from the time it turns off for the picture to reappear. It will stay on anywhere from 5 to 30 seconds before turning off and back on again. I had a repairman come in and he said it was not the capacitors but said he needed more information. At that time the unit would be fine for a couple of hours before it would start acting up. Any thoughts

I have a GE 31GT740 31" TV That turns itself off and then back on every few seconds. There is now a broken (dashed) white line that goes from the very top center of the screen to the right side. The TV will stay on until a comercial comes on and then begin shutting off and back on several times. On cable channels that have no comercials, it will stay on for an entire movie and then begin again when the comercials start. When playing a DVD it will cut on and off at the beginning, when previews, e

My Viewsonic 4785P is out of warranty. Problem is showing in different ways: image stays but sound goes then comes back, or not; everything shuts down and then comes back, or not; other times there is a very strident sound as if the set will explode. A tv tech suggested on the phone that the mother board could be either about to die or corrupted by my cable device and advised to shut down everything for 24 hours. Went very nicely then ... for 3 days and the same thing starts same way again What
