    Mine does the same, but only if it has an input (dvd player). It will shut off after a few seconds.

I have green and redish lines outline everything on my hitachi projection tv

It sounds like a convergence problem and I will attach a few photos of typical sets with this problem.

Confirm the actual model number and I will if it is this tell you what is involved to either do it yourself or give other options.

Could be many things (components) on the board - might be visible, look for burned mark. Careful with the high-voltage leads. if you don't have some knowledge of what you are doing, don't.

Tint on television stays a greenish color.

Tubes are probably dirty. Very expensive fix. Unless it has a warranty or is recently new, look for a local cheap one or one with a smashed screen of the same size. Easy to change the screens out and is very cost effective.

Losing Picture

It sounds like the tv is dieing but since it is rear projection you may be able to fix the problem by replacing the bulb in the tv
