Tempest Posted June 20, 2014 Share Posted June 20, 2014 I just had my 5200 S-Video modded (Electronic Sentimentalies) and the video is perfect, but the controllers aren't working now. The joystick seems to think it's permanently being pressed up . Sometimes I can get it to stop doing that for a second and then I can only move left, but I'm always fighting with it as it still wants to go up. The other directions aren't working at all. It's not my joystick however as they were working fine before the mod. I tested three different joysticks including a third party one and they all do the same thing. Any idea what could be wrong? Is it possibly something with the POKEY chip? Quote Link to comment Share on other sites More sharing options...
Charlie_ Posted June 20, 2014 Share Posted June 20, 2014 It could be.. If you have an older A8 with socketed pokey chip, maybe you can swap another in there. Can you start any 2 player games and see if a controller in port 2 does the same? Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 20, 2014 Share Posted June 20, 2014 Could be something touching the input pin on Pokey (there's 8 for the Pots). Or yes, could be that the Pokey needs replacing. Plenty around at good prices thanks to surplus production and unwanted 7800 Ballblazer carts. Quote Link to comment Share on other sites More sharing options...

Could be something touching the input pin on Pokey (there's 8 for the Pots). There is a wire going to one pin on the pokey, but it's the same sound wire that my old video mod had. I don't think that's the problem Quote Link to comment Share on other sites More sharing options...
adam242 Posted June 21, 2014 Share Posted June 21, 2014 Which 8-bits have a socketed pokey? All 400s, all 800s, all (I think) 1200XLs. Most / some 600XLs and 800XLs - I'm not sure if there's a cutoff production date, or a manufacturing site move that makes the difference, but most XLs I've seen are socketed. None of the XE series have socketed chips. Quote Link to comment Share on other sites More sharing options...
+playsoft Posted June 21, 2014 Share Posted June 21, 2014 Could be that the controller pot inside the machine was mistakenly adjusted instead of the colour one since they are close together. I'm sure there's a post on here somewhere explaining how to adjust it but I couldn't find it - found a youtube video though: http://www.youtube.com/watch?v=NoaiF-xqzEg 1 Quote Link to comment Share on other sites More sharing options...
Tempest Posted June 21, 2014 Author Share Posted June 21, 2014 I'm going to send it back and Joe is going to have a look at it. Quote Link to comment Share on other sites More sharing options...
7800 Posted June 22, 2014 Share Posted June 22, 2014 Oh boy... now I'm nervous. He has my 7800... getting an AV mod done on it. Hope it comes back with no issues. Turn around time is pretty long too. Quote Link to comment Share on other sites More sharing options...

Turn around time is pretty long too. My 2600 came back just fine. I honestly think it might have been something I did to it when I was taking the board out. He offered to fix it for free which is more than generous in my book. I wouldn't worry at all. Quote Link to comment Share on other sites More sharing options...
