This might be your colorwheel or ballast. If its a sound like a whirling metal/glass sound then its most likely a colorwheel malfunction. If the sound is more electrical like a buzzing sound it can be the ballast. Before all this you want to make sure you purchased an original Philips brand lamp because those knocks offs can damage your TV!!
Colorwheel eeds replacement most likley it could also be a fan but I would assume its the colorwheel especially if it was real highpitched sort of squealing sound. You can get the colorwheel and free tech assistance from the guys over at www.tvrepairworld.com
hello
This looks like a colorwheel symptom, does the sound is like a mechanical sound? high pitch sound? winding, whirling or screeching noise ? well if this is the color wheel, what i think it is, it seems that it is not working properly when this happens the DMD board recognizes that it is not spinning at the correct RPM and turns off the Tv for sercurity reasons, so if you want to replace this yourself what i recommend you to do is to open the back of the Tv and search for the colorwheel it can have missing parts or it could be shattered or it could not spin correcty, hope this info. can help you.
the fan motor could be failing. turn it on with the top off. if one of the fans is moving slower, that'd be the one. since this is a dlp projector, the colorwheel motor berings might be on their way out as well. both need replacement.
the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.
