Waterborn Posted June 26, 2009 Share Posted June 26, 2009 We just picked up a boxed 2-port 5200 at our shop. The system is in great cosmetic shape and powers up immediately. When I put in a 5200 cart, I get nothing out of the video or audio. However, when I try to play a game using a 2600 cartridge adapter for the 5200, it fires right up and plays just fine. I know that the 2600 carts/adapter have different pin configs that the 5200 carts. Any idea on how I can trouble shoot or fix this issue? I would hate to not be able to get this system working as it is in such great shape otherwise AND it is a 2-port model. Any help would be greatly appreciated. Thanks!

ninermaniac Posted June 26, 2009 Share Posted June 26, 2009 (edited) Dane, it honestly sounds like it needs a new POKEY and/or ANTIC chip. That, to me, is the most logical solution. Here's the schematics to look and change it if you have another to switch it out with. http://www.atariage.com/5200/archives/schematics/index.html Edited June 26, 2009 by ninermaniac Quote Link to comment Share on other sites More sharing options...
+Allan Posted June 26, 2009 Share Posted June 26, 2009 There is the original Atari repair manual online. It takes you through what is wrong and tells you all the possibilities. Here it is. Allan Quote Link to comment Share on other sites More sharing options...
