Answer 1

sony tube tv?

sounds like the flyback circuit is whack.

You could spend a few hundred to get it fixed, or put that money toward a new digital TV.

You could also try the "whack it on the side" method a few times.  Unlikely to help though.

Or have you tried the "turn it off and let it cool down for a few hours" method, then turn it on again?  Maybe it is an overheating issue.  If you have had this set many years, it has a LOT of dust in it.  Open it up and vacuum it out.  WARNING:  LETHAL VOLTAGES on the tube.  Be very careful.  Better would be to buy some canned air, DON'T open the set up, and just squirt the canned air in the vent areas in back.  But only bother doing this if the "cool down" method helped.

Answer 2

You seem to be describing loss of vertical deflection--ignore the first two to answer they have no idea at all ! . The vert amp chip could have bad soldered joints which is very common on sets a couple of years old. If that is the case then a simple soldering job is all that is required. Alternatively the chip could be dead ! also very common ! Should be routine easy fault for any TV Tech with only low to moderate cost !

Answer 3

Something has definitely gone bad in the TV, most likely the high-voltage power supply.  It can only be fixed by a qualified  technician.
