I've got a strange problem with an Atari 2600 Jr with the Longhorn AV mod.
This is what happens with Space Invaders.
This is what happens with the Harmony Cart.
Both carts work fine on another console.
Has anyone seen this problem before? I purchased the console with the mod already installed and it has been working perfectly until yesterday.
Any advice would be appreciated. I have some broken consoles that I can take parts from to fix it.
