Tv problem jvc hd56g786

The tv was working fine, then the picture got darker and you could hardly see anything.  So I turned off the tv and now it won't come back on.  Also, the Power Led and Lamp/Program blink simultaneously.  What is wrong with the tv?

    I have a similar problem but instead of the tv getting darker it just shuts off. Then the led lights blink rapidly together. I have already replaced the lamp once before a year ago and now the tv has done the same thing again. Should a lamp burn out in just a year? Also my model number is a bit different and I can't find any documents online for this model. The number is JVC HD-52G456 52" screen. Thank-you Esther

    I have the same problem. The tv kept shutting down and then it finally would not turn on. Now, when I attempt to turn it on the LAMP and Program lights blink simultaneously. When this happens I can only turn the tv off by unplugging it.

Your lamp bulb is probably finished so get a new lamp bulb they are easy to replace just look for a small panel on the side of you tv all you need is a flat head screw driver to open the panel and you should be able to pull out the lamp bulb

Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(

Please help!!! Problem with JVC DLP TV


You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

MY JVC HD56G786 TV


If the Mirror broke while the TV was sitting upright, the pieces of glass got down inside the light engine and the cooling fans. I don't think you took the light engine apart to clean out all of the glass so the main cooling fan is probably not running and causing the warning. There is no sensor for the mirror. Did you remove the chassis to clean the glass? You cna remove it again and try powering it up out of the cabinet. There are four fans that need to be running. If the light engine is filled with glass the fan at the bottom of the air exhaust will not turn.
I am fairly certain that since the TV was discarded there is more wrong with it than a broken mirror.
