mitsubishi 62725 with Green Horizontal Lines

[ryandubbz]

My co worker just received a Mitsubishi rear projection hd display from his in laws and he got it to his house and turned it on and now it has Green horizontal lines on the screen spread out evenly all the way up and down the screen. Cant seem to get rid of them. Even with just the coaxial plugged into the tv or with it just using hdmi it still shows the green lines. He plugged in a memory card into the front slots on the tv and the pictures on that come up fine with no green lines, and when you switch to an input thats not in use there is no green lines. Has anyone ever seen this before?

He stated that last night the lines went away and then came back after about 10 mins

I have a similar problem with my Mitsubishi 62825 TV. No discernible green lines until after about 20 minutes from a cold turn on. It does not matter what source (component video, hdmi, coaxial). I am just starting to troubleshoot the TV so do not have a solution.
