lwizardl Posted November 10, 2020 Share Posted November 10, 2020 I have an Atari 5200 system that I have owned for about 4 years now and never ben able to play any games for it. I recently bought a Power Supply and av box for the 4 player system and get nothing from them or the system. I have tried about 5 different games and same results. I am thinking either I have 1) Bad AV box 2) Bad Power Supply 3) Bad system 4) all of the above. So I am looking to buy a confirmed working av box and power supply for my system, I currently do not want to av and power mod the system but I know that will be a future solution if I can not find working cables for them. I own 3 controllers for the system but can not tell if those are working or not yet because I can not get the system working.

bluejay Posted November 10, 2020 Share Posted November 10, 2020 (edited) I see that you've found a spare bottom case. You can buy a brand new replacement power supply off ebay for pretty cheap. https://www.ebay.com/sch/i.html?_nkw=9v+2A+AC+adapter+2.1mm+5.5mm If you can do a video mod and power mod as well you can use standard RCA cables instead of the switchbox and RF as well.

lwizardl Posted November 10, 2020 Author Share Posted November 10, 2020 (edited) Yup I'm going to use that new bottom to do the video mod for it, but I still am not sure if the power cable I have is the correct one or if working. Bought all 3 items (system,av, power) on ebay listed as working but we all know that is not always true that they are working. Added picture of the 5200 power supply and av box that i have so far Edited November 10, 2020 by lwizardl added picture Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted November 10, 2020 Share Posted November 10, 2020 No that is the wrong power supply and will likely fry something inthe siwtchbox and or 5200 if you try and use that. The switchbox and 5200 require DC voltage, not AC voltage on the output. I'm thinking that is the power supply to one of the disk drives. So again do NOT use that PSU with your switchbox/5200 setup.

masschamber Posted November 11, 2020 Share Posted November 11, 2020 I have a bunch of spare 5200 power supplies, 10 dollars each plus shipping but the 5200 has a flipflop chip by the on/off button that regularly fails, changing that should be step 1 Quote Link to comment Share on other sites More sharing options...

lwizardl Posted November 17, 2020 Author Share Posted November 17, 2020 just got in the 2 power cables from masschamber, going to order some 7805 voltage regulators and see if I can repair the system and av box, if not I have a replacement bottom shell coming that I will do the video and power mod to Quote Link to comment Share on other sites More sharing options...
0078265317 Posted November 17, 2020 Share Posted November 17, 2020 The switch boxes are getting rare. I have not seen any on ebay for a long time. Quote Link to comment Share on other sites More sharing options...
lwizardl Posted November 17, 2020 Author Share Posted November 17, 2020 I bought one, but sadly I think it got damaged from the wrong power supply. I opened it up tonight and I do not see any damage to it but I am not getting any video at all from it, but my system does get power because the led light is on.
