2 Problems with my Mitsubishi 65" widescreen projection tv
1. I have direct tv and sometimes when the power goes out or something, the picture has shifted to the left. I called Direct TV and they say its the TV. I've fiddled with the remote to no avail.
2. I also have random problems with shadowing. The screen will get progressively dark then lighter though there is always a shadow to the screen. I usually somehow fix it but am not sure how.
Thanks for any help!

Re: 2 Problems with my Mitsubishi 65" widescreen...
1. THE SYMPTOM IS BRIGHTER IMAGE ON THE SIDES AND DARKER IN THE MIDDLE. THE PROBLEM CAN BE WITH RED BLUE AND/OR GREEN. CHECK FOR PROPER CONNECTIONS TO THE "DAG COATING AND CONNECTIONS TO PIN 9 ON THE SOCKET OF THE AFFECTED CRT. MAKE SURE THESE GROUND POINTS ARE COMMON WITH CHASSIS GROUND

This problems very exspensive to fix.The Light projection Engine have a problems,with a IC design flaw.This problems happen to many Big screen tvs 65 and up have a design IC flaw by many companies like Sony,Mitsubishi,Toshiba and Samsang.Call up Mitsubishi make some kind of deal with them to help u to fix the Light projection Engine by replacing the IC or replace the whole entire Light projection Egine.
It could be a loose component video cable, check your TV menu or another device when it goes out. If you have red in the menu or other device, it cannot be your CRT. The Crt is somewhat hard to replace but if everything goes great it isn't too bad. I usually mark all the yokes and magnets with a marker so I can put them right back in the same place and the picture should be about the same. Sometimes you need to do a lot of adjustment and that is when it can get tricky, kind of depends on how "identical" the new CRT is to your old one.
Yes, you need to replace the convergence output amplifier IC's. They can be ordered on line. After removing the back you must remove the circuit board which houses the amps. Then desolder them and install the replacemnts. If you are extremely lucky there won't be any re-alignment issues with the new amps. Then you should be good to go.
1)possible bad RF modulator (the small box the
A or B signal first goes thru)
2)Bad tuner (mounted on signal board)
3)or missing voltage to run tuner
You could replace signal PCB,but that gets a little pricey.
