Major milestone for me today - finished replacing my chassis. Good news - no smoke or anything - bad news... no image either...
Replaced my wei-ya 2628HR with an identical 2628 (the old one was damaged and shoddily patched together again). I got the new chassis from the same place I got the old one (both used) and I'm told its operational.
Hooked it all up together exactly how the old one was connected. The one exception is that I added an isolation transformer (230v to 230v) as a safety measure. I also replaced the large filter cap as the old one seemed very worn.
Turned it on and at first had no image at all. Messing around with the H and V position pots I got this. Don't know where to start troubleshooting so any pointers most welcome! Signal comes from a pandora box - I can tell its worked as I get sound when I move the sticks...

In case I'm missing something basic, here's what I hooked up:
- Chassis power to the isolation transformer and the transformer to power
- Neckboard to the neck
- CRT ground to the neckboard
- Neckboard cable to chassis
- Degauss to chassis
- Jamma signal to chassis
And a pic of the setup:
