Having an issue with my Sega CD Model 1 where the unti will seem to power on for a second or two (both red and green lights come on) and it then powers off. If you continue to power on the Genesis attached to the CD, nothing happens until you unplug the system completely and plug it back in or pull the genesis out of the connector with the CD and push it back in. I know after reading varying posts on different sites that the fuse on the Power Board can be the issue, but I have replaced the fuse and it has continuity when tested with a multimeter. I also replaced the resistor that sits to the left of the fuse on the same side of the Power Board and it seems fine in testing. I have tested this with 3 different model 1 Genesis consoles with the same issue happening each time. The connector on the Genesis has been cleaned with an eraser and alcohol to make sure it wasnt the issue as well. I also cleaned all the connectors on the CD (the connectors that attach the main board to the CD, the connectors that attach the main board and power board, and the connectors that attach the Genesis to the Main Board).
I am using a 9V RetroVersal Power Adapter for the CD and the Genesis for Power as I dont have a 1602 Power Supply for either. The Power Supply is drawing between 9 - 9.67V when tested.
I read somewhere that the CD Unit could possibly cause this due to not being setup right, but I dont remember the specifics or if that is even a correct assumption.
Looking for some advice here on what steps I can take next to try and rectify this issue and get the CD working properly. Are there things I can test on the boards themselves?
