It is sounding like the CTIA, though have you cleaned the contacts in the cartridge port and checked the fingers are not pressed down?

I cleaned the contacts with a mix of ipa and windex on a micro fiber cloth with a piece of spare pcb. I never thought to look into the cartridge slot for pushed contacts I will look at that in the morning

Good luck, I hope you find something, or I think it's going to be the CTIA.
