Before I forget, here are the different issues with the monitor. After the recap, I reflowed the board, but that didn’t solve the problem. The real problem was the transistor on the green channel, which was completely non‑functional. It caused non‑diode‑like effects with the variable resistor for the green channel. Additionally, the spark gap for the green channel was letting some voltage through, which probably caused the transistor to overheat and the green channel to drop out.
