Mitsubishi XD300U projector projects only black and white

I think its the ribbon cable is loose inside the unit on the main board but I could be wrong.

your best bet is ebay or online sites. https://www.ebay.com/p/Mitsubishi-XD300U-DLP-Projector/66753446

hope this helps

Sounds like the color wheel is not working. Can you hear the color wheel spin up?

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

mitsubishi doesn't have a lamp timer that can be accessed. it will have an on screen message when it gets close, and it'll turn off when it is exceeded.

Hello,
By any chance is your source PAL?
What you are describing is caused by a slower frame rate ie. PAL accompanied by the natural persistence of the human eye. If you reduce the brightness level or turn a light on you will be able to reduce these artifacts.

You would hate watching TV in Europe ;)

Open the case and check the color wheel for chips. Mine shattered and sounded like a broken fan. $+- 225 for new color wheel. Easy to replace and it worked fine.

"I believe your color wheel may have came apart. You should contactmitsubishi for an estimate. You can locate the nearest authorizeddealer here:

This is what i posted on your original post as well. This should be everything to get y ou going to know whether or not replacement or repair is needed.
If you need anything else let me know and if you have a moment to accept and rate my solution on your original problem I would greatly appreciate it.
Thanks,

I have the same problem as philvo. I was watching, the projector was operating normally, I heard a snap, there was a flash of light behind me I believe, and my Mitsubishi XD300U projector went to a black and white picture. That is all it will show now. All lights show normal operation. I would like to know if it is worth getting repaired. Does anyone have any ideas?
