This is the flyback transformer area. If the design has the vertical
circuits power supplied by the flyback, then your height shrinkage could be
a premature sign the flyback is breaking down, or there could be a problem
only in the vertical circuit....changing all capacitors in the vertical
circuit is a common solution to certical problems, however the flyback xfmr
in that chassis is common fail\, so its of not it be mentioned.
