How do you get your xbox 360 to play, on a 65'' mitubishi projection tv,its connected but nothing comes on screen when i put a movie in just a blank screen and no sound,if i'm on a channel,the channel stays on whatever is playing but won't transfer to xbox movie that i want to play i'm stumped''

I'm fairly sure that the 2hdw board is the culprit here. The 2hdw pwb is Mitsubishi original p/n# 935c966001 which has since been substituted to p/n#935c966002 and costs roughly $420.00 dollars plus shipping.
It's a common failure in these units, but it's not a difficult repair for a reputable shop..
Another alternative is to have ashop pull that board and send it in to PTS Electronics for rebuild. That might save about $100.00 dollars.
Please don't rate me badly for the bad news.
Good Luck!

this will need some testing to find out what component has failed and stopped the video processing

SOURCE: No Picture from Component Input #1 or #2 but do have audio via Surrond Sound

Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.

Your component cable is probably switched to the HD setting. You have to switch it back in order to get video when hooked up to a regular TV.
