I’ve read several posts on this site. Impressive !! Several descriptions cover a sound coming from the back of the DLP. I have replaced the bulb…needed that anyway, but I ear a sound like a squeal ?? bearing ?? I can’t tell from the descriptions if it is the color wheel or the large cooling fan. The fan try’s to spin but stammers. The bulb does not light, but it’s new and I think the color wheel does not move. Replace the color wheel, fan or both ?? Any thoughts Thanks
