Re: When the tv is turned on I hear a loud grinding like...
Hi,
May I know if the unit won't power up, has a three blinking led light at the front panel? Also, please check if the grinding noise is near the lamp assembly.

Check front tyres & wheel bearings espesially the R/H/F. Feel tyre for high / low spots on inside & jack up & spin wheel if you get noise while jacked up it is not the tyres but wheel bearing or brake pads but more than likly a crook bearing by the sound of it. It needs to be tended to ASAP
I would suspect your brake pads are worn out especially if you also hear the grinding noise when braking. If you only hear it when turning then have your wheel bearings inspected. Also check the power steering fluid level. It can also be the CV joints are worn.
Hi,If your tv is a dlp you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming ,grinding,buzzing noises.
the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.
Hi, your color wheel needs to be replaced, the bearings fail causing the grinding noise, the new ones use "air bearings" so they are supposed to last much longer, video-tek
Try jacking your vehicle up and turning the tires. listen for any odd noise like a grinding sound, wheels hubs have been known to make a grinding noise when they go bad.
Sounds like the colorwheel (used in DLP projection sets with a single DLP panel) is going bad, either the wheel itself or the bearings on the motor driving the wheel are starting to fail. I would recommend getting a professional to service the TV set.
