I have an Atari 2600 that does not appear turn on at all. I bought it from some guy in a garage sale. I believe he said it stopped working after a storm. I bought a new power supply in case the console had messed up the power supply (I thought the volt readings were off a volt or two).There is no picture or sound with and without a game on it.
I cracked the atari open to look at the electronics. The main board/ motherboard (revision B) seems fine while the controller board seems suspicious. The electrolytic capacitors look fine in comparison to a juicy looking (what I believe to be) a voltage regulator. I found a link for it here.
I am confused about the power circuity layout though. You have power from the power supply, going into the motherboard while going up to the controller board. I guess this means the motherboard is always on when power is applied? Anyways, I think everything on the controller board is grounded to regulator. Thanks for your time!
