BenQ MH630 overheating

Vinko Jan 22, 2018 02:32PM CST


I bought this projector in October 2015 and it worked fine for the first 18 months or so. Now, for the last 3-4 months it is constantly overheating.
Ceiling mounted, plenty of room around it, ambient temp around 68F (maximum; it overheats at even lower room temps, 60-65F).
I recently replaced the bulb and it has not helped.
Basically, after around 20-30 minutes, the projector shuts down and the TEMP starts flashing.
Again, same room, same everything and it worked great for 18 months and then it just won't stay on longer than 30 minutes at a time.
Thank you.

Hello Vinko,

Sorry to hear about the overheating problem you are having. When was the last time the projector was cleaned?

It may very well have dirt/dust/hair buildup in the fans that need to be cleaned.

Would you like to send in your projector in for an out of warranty repair/cleaning?
