35" Mitisubishi - Raster Lines & image pulling down
|
Can't Post

Hello all, I am in a bind... lacking schematics and searching for a suspect bad capacitor (I guess) or something else that this forum may suggest... Recent were repairs were made to the Horizontal output ckt that had failed in a Mitsubishi CS-35305 35" tv. The technician bailed from his job and now I am left trying to help this person out. On startup (after removing power or having been off for an extended period of time the image is pulled down on the screen about 2" or more. As the set has been on for several min.. (15-20) the image moves back up into it's proper position. However this is a slight evidence of raster line (white) at the top of the screen.. If the brightness is turned up you can see evidenseo these raster lines though out the screen. they are about 1" appart at the bottom and get closser and close together as you move to the last 10" of the top of the screen. I suspect a supply capacitor is bad.. I did suspsect a PIP problem based on what I have seen on the internet --- removing the PIP board still has no effect on these lines (obviously I have not real image with that board removed but none the less i can see these lines on the blank display. thanks in advance, casey
