2600 issue on the right controller

Very rusty on much of this so my apologies in advance. I have a regular 2600A and the right controller port will not go up. I have tested this with multiple sticks on Space War and Combat. The only thing I have not been able to test would be paddles on the right port (I only have one set).

 

I took it apart the other week and I don't believe I had any continuity issues for Up on that controller. Pretty sure I remember that being pin 1 but I couldn't be sure. I have the field service manual download.

 

Other than just flat out pin continuity how far down any particular rabbit hole could that issue go?

Could go right down to the chip. In between you check capacitors/resistors, bad solder connections, breaks or corrosion in the traces, the connector. Those sorts of things. Follow the signal pathway from the connector pin to the chip. Check the schematic to see exactly what pin numbers to start and stop at.

Yeah, exactly what Keatah said. If I were to guess, based on personal experience, it's the controller port connection. I've worked on 2 different 2600s that had a pin break between the port and the board, it was the right port on both.

 

Gotcha..... I was grasping for straws on some common issue I wasn't finding, even some curse of death level.

 

Hoping for that due diligence time this evening with the tracing and checks. Thanks for the common sense advice to actually start with common sense!
