I have a samsung dlp model HLP5063wx and have been told that the colorwheel is bad. It has a loud screeching noise then the colors change from blue, to green, to red, etc then the tv just shuts down. I found that the model number of the wheel is BP96-00674A. It doesnt seem that difficult to replace. I did the lamp earlier this year. Any words of advice?
That is a common problem, and it will require you to remove the light engine completely, the light bulb is user replaceable. this is defiantly not. you will need to unplug small wires inside the set and get them back in again, you will need to very careful, this part is extremely delicate.
i found a detailed description on how to do this.
