Irregular fan/color wheel sound- no pict HLR7178W

[genieo51]

My Samsung DLP made a pop noise - the picture began to flicker and went out. Tried to restart and heard it spin up a couple of times but the fan/color wheel makes louder than normal noise and sounds like it is varying in speed - with intermediate squeaks. Finally it stops trying and the 3 lights come on. I tried replacing the lamp but that was not it. I thought about replacing the ballast but I don't hear it trying to click on an off repeatedly on startup. Cooling fan for lamp seems to run fine. Maybe color wheel? Any ideas?

I didn't want to take it apart before I got the new part but I guess I will physically check it out although I'm not sure what to look for. DM doesn't carry the color wheel for the HLR7178WX/XAA they referred me to Samsungparts.com, everyone else seems to have it on backorder. I think the part # is BP96-1103A. It seems like there have been a couple of changes to the part number over time. Can you help me confirm the part number?

The part# you have is correct, BP96-01103A.

Ninja -- Thanks for the help -- I did physically examine the old color wheel and there was a shattered piece missing on the wheel. So I'm now just waiting for the part to come off backorder. Thanks again for all your help!!
