CPS3 Issue

[Chelnov]

Hey everyone,

I plugged in my CPS3 for the first time in a couple of months and this is what I see now. Does anyone knows what this could be?
It happens as soon as I turn the PCB on.

Did you try reseating the SIMMs / ribbon cable / cart?

 

[Chelnov]

I haven't. Let me try and get back to you. Thanks!

 

[Chelnov]

Thanks djsheep! that was it, I wonder if somehow they moved when I got the board out of storage!

CPS-3 is known to be finicky. Sometimes I have to reseat my cart but every now and then I have to reseat the SIMMs too. Glad it’s working

Make sure your 5v and 12v levels are nice and reseat everything.
