Hello everyone! My name is Matt, 40 y.o. and speaking from Brazil. I am a big fan of Atari 2600 and new member here. Thanks for adding me! I have an NTSC console and the board model is Rev. 16, 1980. Recently, I got a problem with the image: the image showed by channel 3 tunes momentarily and then disappears. The channel 2 image is almost OK, but not "smooth"; I can play it, but the image I used to have from channel 3 was quite superior in quality and definition. What seems to be the problem for the image of channel 3? It would be a problem to fix with some adjustment? I'll be very grateful if anyone could help me. Matt.
