Turn power on and I get a "clonk" sound and the set then imediatly
shuts down. Replaced C840 after the power rectifier right before ic
L78MO5 which is the standby and hold circuit. Also replacedL78MO5. It worked fine until I
powered down and let it sit for an hour. When I then power up the "clonk"
and deadness happens all over again.  Please HELP!!!!!!!!!!!!!!

7 Yr old Mitsubishi 60" - Picture Rolls & Jumps until warm

The problem is getting worse and I'm sure one day it will just keep rolling.  I saw another thread about a 70 inch unit that sounded like it might be the same thing mine is doing. It was suggested that it was most likely the PIP module.  It doesn't matter what video is on the screen, it rolls and twists and jumps. Sometimes it takes hours to clear up.  Unless anyone has another idea I'll try the PIP Module repair kit suggested.  Does anyone know a good source for a repair manual?

Red Screen on Hitachi LCD Rear Projection TV

We have noticed that our 3 year old Hitachi 50V500A LCD Rear Projection TV has a red glow coming from the center of the screen.  It has progressed to covering almost the entire screen and has affected the color of the picture.  Everything that is supposed to be white is now yellowish green.  It doesn't matter which input it is on.  Adjustments to the color have little or no effect and it ihas become almost impossible to watch.
