i did check the board and i am getting some readings but not very high.. what do i do if the monter filers are dead.. i can't find another power supply anywhere.. pluse there are black boxes mounted to the side of the cabinet that get really hot are they suppose to get that hot?
The filter caps are dead. Filter electrolytics only last 7-8 years and those suckers are nearly 30 years old. If you want the game to be reliable in the future they need to be replaced. You don't do that by replacing the board, you do it by replacing those caps.
No idea on the other question as "black box" provides as little info as is possible.
EDIT: maybe he means heat sinks?
EDIT2: from chat: turns out he is talking about the HV transistor heat sinks on the monitor chassis - not the cabinet. Yes, heat sinks get hot.
