i cleaned the world out of the connector and cartridge slots on both sides of this. Put in any 2600 game and it stays on for 3 seconds then blank screen.
no cartridge makes the normal atari no cartridge bars, insert a cartridge and it looks perfect, you can start playing is your quick, 3 seconds later, it's outta there!
any ideas? leaning twords it being a cap or something(think it charges up and blah, i don't know)
