First thank you so much for your help.
So if I understand, the TV and connected board MUST be in some sort of Chassis in order to work? Is this because of a grounding issue? It is a 27" tube TV. So yes to answer your question, I did just remove the plastic chassis from the TV and installed the CRT and the board into the game cab. So do I need to put the TV back into the plastic case and cut the case to fit if I can? Also, for my own understanding what does the plastic housing do that makes it monitor work?
