Hello again everyone,

I have an NEC M311w projector that turns on for about ten minutes, then turns off and the indicator blinks red 2x. According to the manual, this means that the projector is overheated. This seems strange to me as none of the vents are blocked and it touches almost nothing.

Background: I bought this projector used maybe a year ago. After six months, I had to replace the lamp/housing (yes, I got a cheap knockoff). It worked fine for a few months, but now I'm having this overheating problem. Do you think it is the cheap lamp? Should I invest in a real lamp, or could this overheating problem be something else? Thanks.
