Hitachi-picture goes out but can still have sound

It sounds like a lot of stuff for a diagnosis, is it an older projection TV? Don't believe it would be the bulb with the fact the sound is affected. May be time for an upgrade!

nope. it just have a loose connection or what they call cold solder issue. if you can find it and resolder it then you can fix it.

tnx 4 using fixya,

This is fixable and if you can find someone in your area that fixes these it will cost you a couple hundred bucks. Seeing how this is a 2007 I would consider buying a new one. They just don't make them like they used to.
