Yes, Both slots are failing the same way.

Have you cleaned the slots and cartridge pins? Use a good contact cleaner.

Check NEO-EO @4F

The slot's gold finger is OK, the cartridge works fine in other MVS.

I'll try to replace it.

Bad news, I found an NEO-E0 to replace it, but it turned out to be even worse, I think maybe this NEO-E0 is just bad.

Continuity is good on all points?
That chip links to both CHA slots.

You may have to correct some errors in regards to the LSPC2 connections but the above gives you a general idea where to check continuity.
