Tempest Posted August 11, 2015 Share Posted August 11, 2015 My poor Atari 5200 has started to act up on me. For some reason it won't turn on all the time (it turns on then it won't for a bit then it will) and will only display in B&W (S-Video, I can't test it with RF). I have a Electronic Sentimentalities S-Video mod on it, but beyond that it's stock. I've done some testing and have determined that it's not the cable, power supply, or monitor, so it must be the system itself. Any ideas? Does anyone do 5200 repairs?

+-^CrossBow^- Posted August 11, 2015 Share Posted August 11, 2015 (edited) Matt If you're getting a BW image then it could just be a loose chorma wire from the s-vid connector back to the mod board. As for the power on and off thing that is likely the little IC next to the power switch. These are known to go out and get finicky like this. I think Best has the IC for sale. I'd be happy to over the 5200 but with OVGE just a month away, my schedule is pretty full right now. Oh..do you also have the composite connection for the video to test with also? When I installed the mod board on my 5200 I did both the s-vid and composite as not every TV has s-video of course.

Tempest Posted August 11, 2015 Author Share Posted August 11, 2015 I'll test the composite and look at the wires this weekend. If I can't figure it out then I'm more than willing to wait until you have the time. Quote Link to comment Share on other sites More sharing options...
Tempest Posted August 12, 2015 Author Share Posted August 12, 2015 Composite gives me color so it must be something with the S-Video wires. I'll crack the 5200 open this weekend and take a look. How do I know if that IC is going bad? Quote Link to comment Share on other sites More sharing options...

Tempest Posted August 13, 2015 Author Share Posted August 13, 2015 I thought I had a 2 Port as well, but I must have sold it. Still have the box though. Depending on what Best sells that part for I suppose. It might be cheaper to buy a junk 5200 off ebay than get the part from them. Quote Link to comment Share on other sites More sharing options...
zylon Posted August 14, 2015 Share Posted August 14, 2015 the power IC is just a 4013 BE and available very cheaply still Quote Link to comment Share on other sites More sharing options...

Tempest Posted August 15, 2015 Author Share Posted August 15, 2015 Mines a 4 port. I'll double check tomorrow just to be safe. Quote Link to comment Share on other sites More sharing options...
Shawn Posted August 15, 2015 Share Posted August 15, 2015 Mines a 4 port. I'll double check tomorrow just to be safe. Best sells NOS motherboards fully populated for only $35. I bought one when my 5200 went south. 1 Quote Link to comment Share on other sites More sharing options...
zylon Posted August 15, 2015 Share Posted August 15, 2015 The only 4 ports with soldered IC's that I have seen were the "last ditch" ones that were sold in mismatched case halves. Quote Link to comment Share on other sites More sharing options...
Tempest Posted August 15, 2015 Author Share Posted August 15, 2015 Well I was messing around with the system today and the problem seems to have solved itself. I'm thinking that the power button was a little dirty or something because after I took the case apart and checked everything it's working fine. The color issue with S-Video appears to be a cable problem (I think). It's all working now so we'll see if the problems come back. Quote Link to comment Share on other sites More sharing options...

Reflow the leads on the power button before you screw it back together. Quote Link to comment Share on other sites More sharing options...
