If this is a CRT television, replace all electrolytic capacitors in the vertical circuit - this fixes 90% of all vertical deflection problems. The capacitors most likely t0 fail are low-cap, high-volt such as 3.3 uF at 50 volts, etc. Quicker and cheaper to replace them all, rather than tracing it down to the one bad part. Total cost if you do it yourself is about $15 tops, and make sure you install them correctly - electros have a plus and minus lead, and must not be installed backwards or you'll have serious blow-upage of the new parts. Before replacing the caps, however, go over all solder joints in the vertical section, reheat them and add a touch of fresh solder. You may end up not needing to replace anything.
