Television and Home Theater

I have a Mitsubishim VS-5017S projection TV, made in 1992, now when power on, there is no picture but sound O.K. Once I pressed "Menu" button on the remot control or "test" button on the front panel, a curved blue horizontal line appeared on the middle of the screen, and this line won't goes away then. And each time press the "menu" button, the blue line will sway a little bit.

When i first power on there are 4 green bars on the left and 6 on the right about 2in. wide and about 3in. apart on a black background.  After a min or two the whole screen is fulled with green lines. 1/16 to about  1 1/4".  vertical.

The red gun on my Toshiba 50H72 can only be moved left and right, but it won't go up. So I have a lot of red in my picture. Is it hard to fix this on my own? I hear it might be the convergence module. Can someone lend a hand with this?

Thanks much!
