Cool Jvc dla hd100

Hi,

I have a JVC DLA-HD 100 projector which keeps shutting down after about 40 minutes of use. I bought it used and the seller said that he had installed a new lamp however forgot to reset it. The lamp shows 2565 hours on it. It worked fine through the winter months, however as summers are blistering hot in Pakistan, it keeps turning off, and the power cord has to be removed and replugged to make it work again. then it goes for around 30 minutes of playtime. Normally I see two lights on the projector; 1. Lamp (Red) 2. Standby/on.
However when the projector shuts down, the Lamp light switches off and the warning light switches on.

I have seen some similar threads for DLP Tvs, but am not sure where and how to look for solving this problem. Any help is much appreciated. Thanx.

If it works fine when it's cool outside then it's overheating, you can try a small desk fan blowing directly onto the projector.

If this fixes the problem then a solution would be to use some PC case fans and a small DC power supply to blow air onto it, there are some mighty quite PC case fans available, the thing to look for is the dBA rating on the fan, the lower this number the quieter the fan will be.

Also look inside to see if there was a fan included with the unit, this may have died thus it overheats, also look for dust blockage on any air vents.
