In Topic: 2600 video full of static - how to fix?

I did have indeed a switchbox in between. I will try it without it next time and using different cables to find out if anything's wrong there.

I found your green cap thread and immediately took a look at the various 2600 PCBs scattered around here. None of them have such a cap, but rather a smaller one that looks like a diode. It's labeled C241 and goes from the ground plane to the input of the 7805 voltage regulator. Didn't know the 2600 was so picky about that. If that's the case, I'll not only change that thing and also add a 0.1 µF cap from ground to the output of the 7805 regulator, as shown in the application note... :o
I'll give it a try and report back! Any other hints? :)

C241 is the correct one, but there shouldn't be a diode in there. Maybe that's the problem. It should have a cap. I use a 224K100V in all the units I repair. They are a little bigger like the ones used in the six switch units

The usual fix is replacing the green "chicket" looking capicitor which cures the warped/thumbprint screen look, but from what you are describing, it sounds more like a RF cable issue. I would swap out the cable and try that first.
BTW, if you are using an old style switchbox, that might be the main cause of your problem! Try a RCA to F type connector available at Radio Shack.

More than likely a bad TIA chip.
If the switch changes shades when you move it, the switch is probably ok.
Replace the TIA chip, which you can get from Best Electronics.

Agreed!
Swap out the chicklet. It definitely cures the problem.
I always put a new one in just to be safe before selling any of my systems.

Doesn't matter if it is a Atari or Sears power pack, as both are the same. (9V 500Ma). The problem lies with the jack in your console. You have to open the console and reflow the solder points under the jack so it is solid and makes contact. Over the years, they have a tendency to work loose from putting the plug in and out so much. That should cure the issue.
