Television and Home Theater

I have a Mitsubishi Projection TV model #WS-55813.
I had great luck following your directions for replacing capacitors to fix the notiorus blinking green light.
now I have a problem that I know will only get worse. when the TV is first turned on the picture has a lot of wavey looking lines on the screen.
this continues for only a minute or so until the picture clears up and works normal. the lines started a few months back, but everytime I turn on the TV I wonder if this is the time that the wavey lines don't stop or the picture goes out completely.

My WS-65909 has lost the green convergence around the outer part of the screen. The center part is aligned, but the green curves out at the ends. Searched and found this site by larry Dillion but the IC chips that he links are marked as sold out.

I have three computers with HDMI outputs that I want to connect to my Mitsubishi tv. Here's the problem, all of the computers display perfectly when they are individualy connected to a HDMI input port on the tv, but if I try to use a HDMI switch to connect to the tv, the image on the tv doesn't change: it seems to stay "stuck" on it's last connection thru the switch. It seems as though the electronics inside of the HDMI switch won't allow a change when another channel is selected.  I have tried three different HDMI swichers, all from different manufactures with the same result.
