Atari 2600 wont play working games?

[seanthemouse]

First off, i'm new here so I will enjoy being on these forums.

 

I've had this Atari 2600 6 switch console for about two years, and it does work pretty well. I have a few games that I can play on it, like Adventure being a favorite.

Lately I've had 9 games that never seem to work on this console left over. They include:

• Kaboom!
• Solaris (kind of works, but only plays for roughly a minute)
• Battlezone*
• Golf
• Canyon Bomber*
• Human Cannonball
• Pac-Man*
• Berzerk*
• Pitfall*

When I bought a big selection of these games (about like 8 ) in February, they were tested on a four switch board (I think it was a Vader). All of those games were working absolutely perfectly when they were tested. When I got home however and put them in the six switch board, five of the eight games weren't working (those games are marked with asterisks) . I get these screens with high pitched sounds and pixels scattered around the screen whenever I turn them on;

I don't understand what is wrong here, since I have 15 working copies of other games that work either perfectly, or usually work 3/4 of the time.

(Adventure is missing its title, and Asteroids is not on the shelf)

I tried to clean the cartridges with Q-tips, but they still didn't work. Then I disassembled two of them to see if anything was missing, but it all seemed intact. I've spent two hours on this and its been very stressful.

 

There's gotta be a problem with the console itself, considering the fact that Pac-Man, one of the best selling games on the Atari, doesn't work.

 

If anyone can help me with this problem, that would be very nice. Thanks.

The pictures of your TV look like the Atari might either have a bad coax cable or a bad RF unit. Mine started looking like that before I did a composite mod.
