Having problems with your Flat Panel Televisions ?

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.

Charlie the proble has something to do with the tv guide here is a response from an older post\012Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was. \012Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.

Hello, I have a Toshiba 57H84R rear projection tv that has developed a problem. Occasionally the screen would turn bright blue for a couple of seconds and then go blank (dark screen, like it had shut off). The red power button would go from a steady red light to blinking continuously and would have to be unplugged, then plugged back in to get it to come on again. One time it did this, there was a bright blue circle in the center of the screen and now there is a permanent yellow spot in the cente

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 JVC HD56G786 rear projection tv is not powering on anymore. I have recently replaced the bulb (as I've done once in the past) and it worked fine for about 4 weeks. This weekend it began powering off on its own after being on for a couple hours and the blue and red lights would flash rapidly simultaneously. Now it won't power on at all- it begins to power up and then immediately shuts down and the lights blink rapidly. The bulb appears fine, but the owners manual says that this issue arise


It may be a fan or a power supply issue, as you said.If there is a fan or other cooling device near the bulb, make sure it is operating. If it is not operating, replace it and see if it works. If it is a fan problem, you will notice becau ... JVC HD-52G786 52" Rear Projection HDTV

Olevia 242-T11 won't power up. A few days before, it started by just not having sound. Continual off and on finally got sound, but after a couple of days of that, it won't come on at all. Unplugged for reset - when plug back in, blue light comes on for just a second and goes out. I'm suspecting the power supply. Is that a common problem?
