If the set jitters only in the picture mode but the on screen menue is
stable you may have problems with the capacitors associated with the picture
in picture circuitry, if your particular set incorporates that feature.
Model and chassis number may help us more further help you.

I read Sam's stuff on 'slight jitter in TV picture' but I do not have a
grasp on it. My Mitsubishi 27 from the 80,s has a slight jitter. I
noticed it when you bring up the display of setting with a blue screen.
Then I was aware of it after that on regular TV. Cheap to fix or it
is to be tossed like everything else these days.

post the model and chassis references, maybe someone will have a tip
database on that model.
