alanwatkins Posted February 11, 2017 Share Posted February 11, 2017 So I just picked up another 5200 system, and it works fine, but the power button doesn't toggle off....meaning when I plug the power supply in, the system is off...it turns ON fine, but then the button won't turn it off. If I pull the power supply out and put it back it, it starts in the off position again. I read some info where the power button can get stuck, but mine doesn't appear to be stuck, I just can't turn the system off using the button. I thought about opening it up to clean the switch, but thought I'd see if anyone had any other advice first. Quote Link to comment Share on other sites More sharing options...
bikeguychicago Posted February 11, 2017 Share Posted February 11, 2017 (edited) Try some contact cleaner on the switch. You will have to open the console up to get to it. Edited February 11, 2017 by bikeguychicago Quote Link to comment Share on other sites More sharing options...
bah Posted February 12, 2017 Share Posted February 12, 2017 When you open it up, there is an ic below the switch. It can go bad and the symptom is that the system will either be on or off and not respond to the power button. This is likely in need of replacing. Don't hold me to it because I am going by memory but I think it is a 4013 chip. B Quote Link to comment Share on other sites More sharing options...
alanwatkins Posted February 12, 2017 Author Share Posted February 12, 2017 Well, I got the button working...apparently it just needed to be cleaned - I'm not sure why pulling the power out and putting it back in always seemed to fix it, bu the button is fine. Of course now it doesn't play any games....it will take a 2600 adapter and play 2600 games through that, but no 5200 game works. I opened it up and re-seated all the chips...not sure what else to do with it - probably going to sell on Ebay for parts Quote Link to comment Share on other sites More sharing options...
0078265317 Posted February 12, 2017 Share Posted February 12, 2017 That is so weird. Is it a 2 port? Quote Link to comment Share on other sites More sharing options...
zylon Posted February 12, 2017 Share Posted February 12, 2017 The 2600 adapter uses only the power and video circuits of the 5200. Your machine must have a problem on the logic side, possibly in the 4013 BE. That IC sends the power to both the video and logic circuits of the system.

alanwatkins Posted February 12, 2017 Author Share Posted February 12, 2017 Yep, a 2 port. I've got a working 4-port...this was just going to be an extra console....but I guess I can sell it to someone that can fix it. Quote Link to comment Share on other sites More sharing options...
