Atari 5200 2 port issue.

[zylon]

Green shifting to brown is a common voltage regulator symptom. I'd still look into the ANTIC chip, the upper right of the 4 largest chips.

I started on some of that toubleshooting with the field manual, it appears some of those tests require a diag cart wich I do not have. Projects are fun! If I cannot get it working maybe I will farm it out to someone who had more repair skills then me!

 

Any takers?!

 

Like I said I have 2 working 4 ports just no 100% working controllers! lol I want to play some HERO, M-Revenge and Star Wars Arcade!

Maybe I will try to replace that as well, Anyone know were I can get a new ANTIC?

Try checking the voltage regulators, those are much cheaper to replace than an ANTIC chip. You should be getting something close to 5V on the outputs of both regulators.

Best electronics would probably have it. You might consider asking in the 8 bit section. Since the 5200 / A8 share the same chips someone might have a spare antic to sell cheap. I got a GTIA chip for one of my 5200s that way.

5200's are cheap enough to buy than to spend $ to have someone fix. My 2-port's colors aren't all that great anymore either, although they don't shift after being on awhile.

But yours play's this one does not.

 

 

I also aquired an Atari 400 computer that is doing something very close to what my 2 port is doing. lol maybe I am cursed to not own the 8bit Atari family
