Neo Geo AES Graphics Glitches with all games

Hi all, my Neo Geo AES is having some strange Graphics Glitches with every game.The games eventually work but I️ usually have to reset the system a dozen times before they work properly. I have cleaned each cartridge and the console using Isopropyl 90 and a toothbrush, also a credit card with cloth for the insert. Any advice would be greatly appreciated.

Carefully take the boards out of the cartridge and clean the contacts with a pink pearl rubber eraser. This is the only reliable method I've found for cleaning cartridge games and I do it to all the games I buy.

Thank you, ill give it a try.
