Danijel:
Well BEFORE you try to adjust anything in the service menu you should first
attempt to repair any possible faults with the vertical deflection area of
the circuitry..... most likely faults causing vertical size problems are
out of tolerance, dried up, or high ESR electrolytics ... and cracked, dry,
cold or faulty solder joints in and around the vertical output circuitry.
