Sounds like the color wheel has failed. Can you hear the color wheel spin up when you start the projector?

This projector is projecting a red color throughout. What should I do to correct the color? It has been turned off for about an hour. Please advise. Thank you.


The EX240U uses a DLP imaging chip and a rapidly spinning six-segment color wheel (red, blue, green, white, yellow and cyan) to form the image. It is likely that the spinning color wheel has stopped with the red filter in front of the chip. I recommend opening the projector and see if you can coax the wheel to move and maybe it will spin once again. if not, it may be the wheel motor or the circuitry that affects the timing of the spin - either way, it will take a trip to the repair shop to fix.

Hope that helps.

I have lines and black spots all over display


Most likely you have a failing DLP chip. The DLP chip is the one that forms the image that is projected onto the screen. Search for "Mitsubishi Black Dot" in your search engine and you will see you are not alone. Apparently, a lot of DLP chips in Mitsubishi products are failing. With the low price of projectors these days, your best bet is replacing it. If you want to repair it yourself, the chip will run you about $200 to replace and may require soldering.

Hope that helps,

This is a dmd chip going bad. Here is the replacement on a very similar model. You would need to verify your chip number to be sure. Love to know if it is the same as the 250 and it probably is. http://youtu.be/775YOs-aOPc
