Adjusting the colors of Atari 2600 – Part 3

Continuing to articles about Atari's color adjustment 2600, I speak today about adjusting my last Atari 2600 that still lacked test fit: the Atari 2600 Polyvox of an external source.

I recommend reading the other two articles of the series before continuing:

First, to open the console, I used to do something I hadn't done when she gave it to me and I did the cleaning. This time open the metal protection against interference.

This Atari Board 2600 appears to be original Atari. Inside there is a metallic protection plate, welded in some glued in and points a sponge to prevent her contact with the motherboard, at the same time that keeps fixed. Looks like a beautiful gambiarra the Polivoks.

I think this has been one of the first models of Atari 2600 released in Brazil by the Polivoks, because the original plate of Atari contrasts with that of my other Atari 2600 the Polyvox, with the built-in source, that uses an own plate Polivoks.

When I put the Harmony Cartridge and open the Color Bar Generator, to my surprise the colors of the two parties were already combining, showing that the adjustment of the trimpot This Atari was already perfect.

But, instead of the Green that you see in the Atari VCS with mod for S-Video and Composite Video, on the Atari 2600 Polyvox of an external source If you see anything more to Brown.

As the console was warming up, the bottom was changing tone, as expected, getting pretty Orange.

I noticed that in the games got a little strange colors, the Enduro stayed with that very dark green and with the Panel in magenta. These colors look wrong. In Pitfall colors also get weird, drawn to the Brown where they should be green.

I could find that there is something wrong with this Atari 2600, that is not the trimpot, but the fact is that the color that appears at the top of the Color Bar Generator is exactly the same that appears with the Atari 2600 Polyvox with the internal source. In it I even set the trimpot for Enduro colors would be nice, but it is not correct from the point of view of the test Color Bar Generator, and probably reduced the amount of palette colors.

Now I really was even more in doubt. Had my two Atari 2600 the Polivoks exactly the same problem with the colors? Any part that wears out with time? Or is the transcoding to PAL-M changes the palette of Atari 2600? If you have an Atari 2600 the Polyvox, help me clarify this doubt.

I still need to test these two Ataris the Polivoks in LCD TV, because as the palette of Atari 2600 pull to green on the LCD, It is possible that an Atari that pull the Brown naturally stay good in an LCD TV.

Updated: Forgot to mention, but the problems with noise in the image that I had mentioned in the previous article have mysteriously disappeared in this Atari 2600.

I also did a test with him on LCD TV, but the colors are horrendous on it:
