These old CRT's are not my cup of tea but since i have a bunch of these cabs laying around right now i figured i would try and salvage atleast one of them and retrofit LCD's into the rest of them. Anyway, I got one with a clear good color and working touchscreen but for whatever reason, the H size will not adjust. I swapped the adjustment board with a couple from the other cabs but that H size is the only one that wont adjust. I did not notice any blown caps on the CRT boards but im not sure exactly where i should look so i could have overlooked it. Hoping someone knows more about these and can help narrow down the culprit. CRT is TATUNG type 66 G20.
