Hi everyone,

I'm looking for some advice regarding an Optoma projector.

I bought it used a few months ago and it has worked fairly well overall. Since I got it, it would occasionally shut down due to what seemed to be overheating. To avoid that, I started using it in an air-conditioned room or with a fan nearby, and it worked fine for quite a while.

Recently, a different issue appeared. When I power it on, the projector starts normally and displays the Optoma startup logo, but it never reaches the main menu. After a few seconds, it restarts itself, shows the Optoma logo again, and keeps repeating this process in an endless boot loop.

Has anyone experienced something similar or have any idea what might be causing it? Could it be related to the power supply, cooling system, temperature sensors, firmware, or some other hardware issue?

Any suggestions would be greatly appreciated. Thanks!
