My Toshiba CN3281B was working perfectly. I moved the set from one room to
another and as soon as I reconnected it, the vertical control is too large.
It's not terrible, though the channel numbers at the bottom of the screen
and occasional head shots leave the tv news anchors a bit flat headed. Can
anyone provide some guidance? Thanks in advance. Paul

Bad capacitors in the vertical circuit due to age, common problem on
that era Toshiba.
If the color and contrast are still good the tv is worth having
repaired.

Purely coincidence that it happened after you moved the tv set.
The capacitors got cold while the set was unplugged and then exhibited
the problem worse than before.
