Donkey Kong

Question from James: Greetings video repairs, get ready to scratch your brains on this. My video guru Wayne has just restored my Donkey Kong. It looks sweet BUT Houston we got a problem. I have a jitter on the game board somewhere. It’s not the power supply or monitor / chassis. I’ve used 2 Nintendo chassis and another tube to be safe. We’ve installed new caps on power supply and we’re getting steady voltage across the board with a scope. Removed FL to check interference. There is a filter etc. About 18 plus hours trying to figure this out and I’m running out of hair. Game plays perfect coins up, audio works, picture crisp and bright. Just have a image jitter, possible sync problem and it’s kinda annoying. Anyway to know what would cause this I have a short clip of this. Please let me know your thoughts. Thanks, James from Central New York
