Color problems?

[AskewTV]

Hey I am having problems with the color on my Atari 2600. On pitfall everything looks green, and on some other games it just doesn't look anything like stella. Is it because I used a male (phono) to female (coaxial) piece? I already tried adjusting the color by opening my Atari.

 

Model: 2600A

Some pictures might help.

If you've already adjusted the color pot on your 2600, you might have a bad RF modulator, bad solder connections to the modulator, or some other electrical fault in the machine. As Thomas says, photos of the screen might help diagnose the issue more precisely.

Also a failing TIA will do this. I've had to replace at least one TIA in a H6 model because several of the colors were off or starting to do rainbow shifts during game play after a few minutes being on.

Okay, I will take a picture as soon as I can get my hands on a phone charger.

Ntsc color encoding ... never the same color

 

You can tweak the color temp pot inside the system till it looks perfect, until you run a different game, best to aim for the middle

Also, can you help me with one other thing? This may be normal, but sometimes I start a game up it looks like it has problems connecting to my TV, and when I turn it off it does a static sound for a second.

 

EDIT: I made a video of it:

sometimes it does it for longer periods of times like 5-10 seconds. Edited August 18, 2016 by AskewTV

You can try open te VCR and read all its OK? No dust, trash, little pieces of metal, desoldering pieces, etc. Maybe only little maintenance and clean of contacts is the solution, if the problem persist, somebody have the solution.
