BenQ HT1085ST DLP Projector Overheat Repair

Описание к видео BenQ HT1085ST DLP Projector Overheat Repair

Another BenQ HT1085ST. This one would run about 10min and then shut down from a temp error. The exhaust fan was fine as were the RPMs of the rest of the fans, yet not enough air was moving though the lamp.

I found the blower fan had dust caked onto the blades preventing efficient airflow. Once I cleaned them up, it ran much cooler.

Fan RPM is not always an indication of fan condition. The amount of air they move is also important if not more so than the RPM.

If you need a lamp for one of these, this is the same brand of lamp in the video. https://www.purelandsupply.com/benq-l...

Thanks for watching!
