Found it!
Also found my old sega genesis
The one I just found has no screen so I am sure it is the bad one.
The other one will be fine but I do see that the gasket for the screen is damaged in one spot about a half inch or so - probably came apart when I removed it. So you might want to ditch it completely on that one or replace it.
Do you need the stock connector or did you keep your old one. I cut mine to install the z32 but I left an inch or so of wire on it in case I needed to use it again.
