We have the factory manual on this set if it will help. Nothing in Winstips
that sound like this problem.

> Need someone that is familiar with this set to help. It will not start
unless I go through a routine of unplugging any one of the three combination
convergence /vert yolk plugs. Then plugging the a/c cord in and then
plugging the yolk back in. Now the set will start up. If I shut the set off,
it will start up again if I don't wait too long. If I unplug the a/c, then I
have to remove any of the yolk plugs and repeat the routine. The standby
voltage does not come up unless I do the routine. One other consideration,
the print calls for +&- 25 volts for the convergence amps. This supply is
putting out +&-40v in standby and +&-33V in run. This doesn't seem normal,
but find nothing. Other standby supplies are normal. I have been going
around in circles on this thing too long. I have replaced the amps on the
convergence amp board and a 5v regulator. Every ave. I go down ends up a
dead end. Have heated and used all my freeze. Have more coming. Tried to get
help from factory,wont ta
