Started with a ticking monitor. Replace shorted HOT, C308, C314, C315, C422 and C316 which is a 25v 22uf bipolar. We don't have any 22uf bipolar caps and the parts chassis are missing C316 already. I made a 22uf bipolar by soldering the negative leads of two 47uf caps together and installed it.
Powering up showed a solid red screen. Pulled chassis and found one leg of R948 had lifted. I soldered it back down.
Powering up showed game video (California Speed), but focus was horrible. I think this game had focus issue in the field.
Adjusting focus on flyback changes focus from HORRIBLE to playable but still out of focus.
Is this definitely a bad FBT or can the focus circuit be getting a low/high voltage that keeps it from adjusting to the correct focus?
If it can be voltage please let me know which caps etc to check. I don't know where the focus circuit is on the schematic.
Thanks!
