No picture I have the 46" Mitsubishi WT-46805. It has not been used much in the last year or so as I have been travelling a lot. A month or two ago, I noticed that one of the colors (don't remember which) would occasionally pull out about an inch or so above the other two, but would only last a few minutes. Two days ago when I came home and turned it on, I got no picture. The power light comes on and I hear it click. I tried changing inputs, then noticed if the input source was noisy, I would see some lines at the top of the screen just when the channel/input changed, then they pull all the way to just above the screen except for just a little light being visible at the very sides. That sounds like no vertical deflection - is that right? Is this possible to repair with a circuit board replacement? Thanks for any help.
