K4600 that was in unknown condition after being stored for years, had vertical collapse when I tested it. Decided to do to capkit since I had one on hand. Afterwards, this is the best I could get it to look like while fiddling with the sync pots.



This image is relatively static for how garbled it looks. Even though its appears un-synched, it's not moving, just obviously not a good picture.

B+ voltage is 127.4
Pulled black level pot and tested it out of circuit, remounted on the back.
Screen pot on neck board works for adjusting overall brightness.
Tried both V+ / H+ & V- / H- sync signals from TPG, no differences
My 4600 must be an early model since I'm missing the jumper wires for vertical/horizonal positioning
Already removed & reflowed solder for all interface boards & headers.

Any ideas where or what I should check next?
