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,

I have a zenith rear projection tv model r56w36. It won't turn on. When I remove the back panel and turn it on, I see a bright flash coming from the middle bulb on the right side of it where it looks like a wire is connected and then I hear a click from the power board. All the conductors appear to be fine. No bulging or anything but it won't stay on. Please help
I have a Visio P50 HDTV20A 110-240V-,5.0A,50/60HZ. My husband was try to hook a USBcord it the back of the tv and he thought the service 1 slot was the place to plug it in. He didn't force it at all, it only touch the area and when it touched the tv went off. You can hear a faint humming sound and a light backlight but it doesn't appear to be getting power. The front lights aren't on nor will the tv come on. Does it have a reset button or did he blow a fuse. How much will that cost to fix and

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?

TV was working fine. Shut it off, all power went, no red light or any other sign of power. Will not turn back on, as if no power source. 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. This TV is not over used (2 adults), TV is 2 years old.

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 Vizio VP42 HDTV (inside says LG PDP42X3U400). One day I turned on the TV and heard a pop. I took off the back of the TV and inspected the main power supply board (P/N 6709900019A). Capictor C802 had totally blown up. The tv would not power on at all. I removed U801 and when plugging in the AC cord I heard two relays turn on and then back off after 1 to 2 seconds. I gave up troubleshooting that board and bought a new power supply board. When I installed this board and plug in the

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.

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.
