Hi all, have had this MS3 cart for a while now, worked for a while on location. We swapped it out and left it alone for some time, when it came time to test the cart again we ran into this issue. Loads to garbled graphics, idles for a few seconds and then restarts until we turn it off. Contacts have been cleaned on both the cart and the board. Testing on a confirmed working MV1A which ran two other carts perfectly. I understand that the daughterboard version of MS3 is trouble, but would appreciate any advice you all would have.
