No picture or sound

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

That is likely the color wheel assembly and not for the DIY'er... Find a reputable tech to take it to and s/he should have it on it's feet in no time. They will need to order the color wheel Part # Bp96-00250a and costs about $108.00 plus shipping and maybe core then your labor. But it's a well worth it repair...
