Sharp 65dr650 rear projection tv makes loud nois...

I have a Sharp 65DR650...I got screwed on a trade and didn't do my homework. After calling Sharp I was directed to Anrews Electronics (800-274-4666) in Ca. I spoke with a nice representative who informed me that the "Optical Engine" (what you need to buy because the Color Wheel itself is not available alone) is just over $1250!!!! To make matters worse, there is a core charge of $1480, which you are charged at the time of purchase....when you ship your rebuildable core back to them you get refunded the $1480. So basically, with the Service Manual ($37) and the upfront costs on the equipment you are looking at close to $3000 out of pocket.....and that's if you put the unit in yourself!!!!!!

I also read somewhere online a guy who remved and rebuilt his own color wheel using a similar models shaft/bearing assy. Sounds tricky, but if it can be done I will try. If anyone has any info on this process PLEASE let me know!!!

Same problem...what do we do?

yes, we have the same problem

I have the same problem. Just replaced lamp, powers up, good for 30 mins, then quit ... wait 5 mins it powers on again, then good for 3 mins, picture starts to flashing,then quit again... you can hear the humming sound become unstable, just like keep pushing and releasing gas when you ride a bike... Believe the light engine is broken... anyone knows how to fix this?
