hourglass picture

[tbrown2155]

I have a 1994 zenith projection tv, pv4663mk and sometimes the picture goes in on the left and right side of the tv. It is kind of like an hour glass. If I pick up the tv an inch and drop it, the picture sometimes pops back to normal. Any Ideas?

remove deflection pcb and check for poor solder connections around flyback and horizontal output transistor.
