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
lk to
me. Not Sharp ASC. Sorry to write a book but really could use some help.
