(2) D9200 Issues - Vertical Line one monitor, one with no HV.

I have a D9200 with a horizontal collapse.

I've tried everything I can think of - caps, transistors, diodes. Can't
find anything bad on the board yet the monitor is only displaying
a vertical line in the center of the screen from top to bottom.

Coils read around .9 ohms for horizontal, 3.2 ohms for vertical.

Tried just about everything but swapping the flyback.



The second monitor has no high voltage. Everything in HV section
appears good. I had a bunch of shorted parts - Q413, Q418, Q417 and
the diode and resistor that usually go bad. Replaced everything, monitor
does the usual click routine, but no HV. The tube is glowing, all voltages
are good. Even replaced the flyback - nothing !

Any ideas ?

Thanks,

JD
 
D9200 #1 - Have you checked the horizontal width coil, and the ribbon cable and connector to the remote board? Or done a complete cap kit yet?

D9200 #2 - Q425 (the HOT) is probably shorted. It's a 2SC4770 (NTE 2324) transistor. Have you done a complete cap kit yet?
