Try replacing the electrolytic caps on the video driver board. It doesn't

Actually this set has just a single circuit board in the bottom of the
chassis. (I've gone into it before to tweak the vertical height which
started shrinking a bit a few years ago.) Replacing the electrolytics
is probably not a bad idea, though, they're pretty likely to be drying
out at this point and starting to cause problems.
