jetset Posted April 9, 2019 Share Posted April 9, 2019 My 5200 took a shit a few weeks ago. Not sure the problem, I have 3 functioning switch boxs', a power supply that works (measured with a multimiter), but somehow the unit still doesn't power up. Yes, I know the power mod is easy...but I suck at this stuff and would much rather pay someone.Anyways....a long shot, but figured I'd see. My next step is selling off my system. Too many things to do in a day for me to fart around with something I don't know how to do. TIA! Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted April 9, 2019 Share Posted April 9, 2019 If the switch boxes are good and the power supply is good. Then the only other quick fix is to replace the flip flop IC for the power on/off itself. It is nearly always in a socket on the 4-port units and easy to access. Only have to remove the top cover(taking care to not let the controller cover fall out) and it is right there by the power switch. https://console5.com/store/cd4013-flip-flop-ic-atari-5200-power-stuck-on-or-off.html It is a very cheap component to replace out. Look around and see if there aren't other things you might want to grab to make the shipping worth it more. That is what I would try first before anything else.

jetset Posted April 9, 2019 Author Share Posted April 9, 2019 Thanks, yeah I found the chip (I think). It came right out, I was gonna switch it out with an old 4-port board I have, but the chip in that one is soldered in. Thanks for the info.

+-^CrossBow^- Posted April 9, 2019 Share Posted April 9, 2019 You have a 4 port with a soldered power flip/flop IC in it? Interesting...does that 4-port have an asterisk on the SN by chance? Either way, it is a cheap part to get and always good to have on hand because those ICs are prone to failure. Quote Link to comment Share on other sites More sharing options...

The pic is my current (dead) board. The old (also dead) board has that same chip in the same place, and yes it's soldered onto the board. I ordered one frm that link.

Iwantgames:) Posted April 10, 2019 Share Posted April 10, 2019 The most active members are from the south. I'm central but I go to the south meetups as they do them more often and it's a great group. Quote Link to comment Share on other sites More sharing options...
zylon Posted April 10, 2019 Share Posted April 10, 2019 Some of the final 5200's assembled were 4 ports from leftover parts and many of those had soldered IC's. Quote Link to comment Share on other sites More sharing options...
