Customer Question

We have an Epson BrightLink 450 wi projector which is overheating. We had it opened and expelled accumulated dust. But it continues to overheat after 20-25 minutes. If you can solve the problem I'll be delighted to pay $28. Jacquelyn Williams P.S. I am in rural Haiti.

Hi Jacquelyn,

If you have removed the dust and the vents are unobstructed, but the projector still indicates that it is overheating, then the thermal sensor may be faulty and it will need to be replaced.

You can try measuring the internal temperature with a thermometer - this will help to confirm if it is overheating or not. If the temperature is really not too high, then this confirms that the thermal sensor is faulty.

Where do we find the thermal sensor and how much does it cost?

Is this something we can order on line? Where?

Hi Jacquelyn,

You will need to contact Epson and request a replacement sensor from them. They typically cost under $20.

Just one other thing to check as well - make sure the fans are working; if they are not, you will also get overheating error.
