> Working on this unit with no print, (before shut down) Found no
drive to the vert output TA84303K... On the main board, the set uses a
TA1268 chip pin 22 (vert drive) has a nice clean 2v p/p at turn on.. But
tracing thru the main board I can't find it anywhere else. Any help greatly
appreciated or a print of the main board.. I had the same model a few months
ago with no vert/sweep and found a small resistor in the vcc feed open..
