One step forward, two steps back.
I plugged the unit in and noticed a wavy blue screen. Playback was successful, but I needed to figure out what was causing the underlying noise. I started checking from the composite out and the electrical adjustments (C Sync & Video Level) were way off. I began adjusting them to their proper levels using GGV frame #19,900, and playback abruptly stopped. Weird things were happening with the servos. I went looking for more bad caps and found C902 on main board was same leaky 10uF 16V cap. These do not match the other black capacitors and look like knock offs. Replacing that still resulted in weird electrical issues, so I'll have to keep hunting for more.
