I've been working on this WG6100 for the last couple of days. I made some progress but have hit a little wall and need some help. The picture below is where I'm currently at. The Tempest game video can be seen in the small sliver on the monitor.

Details:
Spot Killer is On
I got Chatter
181 v on pin 5 of P900
28v+- on pin 1 and 7 of P900
Fuses intact

All the frame mounted transistors were replaced along with couple of other components and caps. I also tested a bunch more.

Any help would be appreciated.

Thanks
 
Check the wiring to all your deflection transistors on the frame. It's common to have one come loose, especially while changing them.

Also, did you reflow all the pins where those connectors plug in? It's very common to get cold solder there...

All the pins were reflowed. I'll do a check of the wiring for a loose connection.

Also, I bought this non working so I suppose the board could have issues.

Thanks
 
Or, rotate the monitor 90 degrees, and you'll have the same problem ;) .
