Re: 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.

Insects crawling up the mirror on the inside of the TV, ready to be killed.

there should be a cheaper solution. maybe look on the net for imformation on ants. you just have to convince them to leave! The tv when its on is warm. you need them to walk out of the tv as the could cause faults if they die in there.

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.

How do i clean the mirrors on a big screen tv

In most cases you can remove the back of the TV and get up inside the cabinet to clean the mirror. Windex works great on any glass mirror, but if it is mylar, a less harsh cleaner is better. If you have a newer digital type projection, you will likely have to go in through the screen to get to the mirror and it is much more difficult. I can instruct more depending on type and model of tv.

How old is your TV?
Lamps in DLP TV has specific working hours and physically lamp will look good but won't give light ( actually consume more current and protection circuit stops power supply)
Thank you.
