Test on sharp model 65dr650 rear proj. t.v is ther a simple test i can perform to tell whether my lamp or color wheel is bad...any way to tell difference between the too by a simple test....or maybe i can get brief description what to look for between the too....

If you are comfortable - you can try taking the color wheel out of the tv. Pop the motor apart and clean all the residue on the bearing/spindle. Then lubricate and put it back together. Search on google for how to do this.

There is a company that replaces the motor. Search on ebay for them.

You can buy the color wheel from [email protected].

U hear grinding noises,squiling noise,before colors fades in&out,turn to Black&White picture,than died?Yes,than ur DLP tv have a colors wheel,it defective,require replacing.The colors wheel is spinning off of it motor axis.The tv tech,should be hire for changing the tv colors wheel.

That humming noise was your color wheel going bad. It is part of the optical engine. I am not sure if you can replace it separately. In any case this is complicated and expensive repair.

your color wheel needs to be replaced

I would return that lamp and get an original

It is in case next to the lamp. Its thin cable sticks out from the case. You will to open the back panel of the TV, check for cables, remove screws for the base on the right, then pull out the base out. You will have to be very careful removing screws and gentle when replace the color wheel. Hope this helps.

Looks like we all got screwed with this TV. Mine just started after 2 years and now it's getting louder. I think I rather call my lawyer than Tech. This product is NOT build properly and someone should let the company know about it.

i have a 56DR650 and it does them same thing. It is still under warranty but where i bought it, they said they can no longer fix it so they are giving my money back. the problem has to do with the color wheel inside.
