I am in need of some technical expertise with an issue i am having. I have a Mitsubishi WS-48311 Rear Projection that seems to be having a heat issue. When powered up, the TV plays fine. No issue till after about 20 minutes then the entire screens starts to jump. Not bad at the beginning...but increasing as time progresses. I can actually complete an entire movie....but the jumping still continues. The entire screen does jump. When the menu button is pressed....the menu jumps also.
As far as what has been done....almost all caps on the power board and dm board have been checked for leaks. IC8C01 & IC8C02 have been changed with new (made no diff).
Suprisingly though....coolant spray on the convergence IC's will cause the screen not to jump as bad.
Kinda running out of ideas and need some of your help. Thanks in advance for the help.
Mike
