All,
TV in question recently developed following symptoms. After being on for 20 minutes or so, the sides of the image snap down for an instant before returning to normal.
Performed color aligning and convergance aligning via the on-screen menus, but that did nothing to correct the issue.
The problem seems to be intermitant. It goes away for a while and then returns.
Since the set is so large, I am looking for suggestions on what the problem might be so that I can either:
a) repair myself b) describe suspected problem to repair tech (if one can be found) c) pull appropriate boards for repair
TIA, Douglas
