Problem 4slot MVS review/repair

[retrogamingblog]

Hi all. I have a 4-slot MVS board that has started playing up. Sound and graphics are disjointed. I’m looking for some one to diagnose and repair. Any help much appreciated. I’m based in UK and can ship.

I had all sorts of issues with dirty slots on this boards. Try not to push the cartiges all the way in and clean the contats. The blue part of an eraser works great on edge connectors.

Also check the solder and traces on the underside of the cart slots as the flexing from inserting and removing carts can cause them to crack.
