I have a JVC 56" projection TV. I recently replaced the lamp and housing unit and since then the picture has been red. At first it would go back and forth from being normal to having an awful red tint to it. It is not the entire screen as if the red is set too high. Anywhere that is supposed to be blue is now red and the shadow to anything is red now too. I have tried changing the picture settings but that does nothing either. Please help :(

Sounds Like maybe a cold solder joint or intermittant connection.

Model number?

Always check the connections just to be sure.
