Picture coming in and out when toggling POWER cord?

[hiitsbrian]

Still troubleshooting 2 Ataris. I am just messing with 2 motherboards and 2 sets of AV cables (and 1 power adapter). I am now realizing that the only way I can get either of them to work is by BARELY plugging in the ac adapter. If the tip is inserted, you can see the picture, but once you push it in as far as youre supposed to you get a black screen. This makes NO sense to me as this cord is just the power cable and isn't even connected to the television. I'd just keep it barely plugged in but it's seriously so little that you can plug in that theres no way I could get it to stay like that, and if I taped it I'd end up pushing it in too far. Anyone here ever heard of this? Know of any solutions? I'm baffled.

It could be a bad power cable that just happens to be in the right place for continuity when the plug is part way in, have you tried plugging it in all the way and wiggling the power cable while holding the plug steady? If not try that and see if the power appears to be going on and off, if it is that is probably your problem.

Alternatively it could be a worn socket or a bad solder joint on the socket that is being move to where it does not make contact when the plug is fully inserted, you could try re-soldering the joints for the power socket or replacing it. Not 100% sure what kind of socket you need but from images of the PSU it looks like a 3.5mm mono Jack - I am sure there are plenty of people here to correct me if that is wrong.

Replace the voltage regulator.

I know it sounds weird, but search jump starting a Atari.

Fixed my system.

Ok, I can see that..

This system makes no goddamn sense. When I'm able to et the picture in, the controller doesn't work right for different games. For example, I can use the action button to jump while playing Pitfall, but the same controller won't fire your weapon while playing Space Invaders which uses the same button. The Hell!?

System needs a TLC from a technical expert.
