I have a Zenithin for repair.. No video, I have HV and sound and if I turn
up
tyhe G2 the tube is lit with slight retrace. It has a 9-1643 video board
but I
can't seem to get anywhere even through PTS. I have no schematic on this
and
would like to fix it. The drivers on the CRT board are cold and I get
about 212
volts on the collector If that is any help.. Thanks

Or, you could look for a bad resistor, and possibly a bad diode, for the 200
volt line.

If a resistor has changed values, chances are that its being cooked. try a
higher wattage one next time

Thanks, What I found were 2 open resistors on the sweep board. One was
open and
the other changed in Value. Thanks again
