repetto74 Posted September 9, 2017 Share Posted September 9, 2017 (edited) Hi guys, I picked up today an Atari 2600 model CX-2600. I had this for few bucks without any guarantee it is working. Hi hooked it up to a standard CRT TV with the RF antenna input at the back but I do not know how to tune the TV. The console does not have a power up light so I cannot be sure that power is applied when turning on the power switch. What should I check first to ensure that the board is correctly powered? I was maybe thinking to go for the composite mod before and check if there is an output on the TV through the video composite inputs. There is also a Channel Select switch at the back for A or B channel selection. What does this mean? Any suggestions?

repetto74 Posted September 9, 2017 Author Share Posted September 9, 2017 (edited) So I managed to tune the TV to the have a display. Poblem : -image is in black and white even with the switch TV TYPE set to color (the TV is a color one of course). All other functions seem to work and joysticks will work. I did select a manual + a fine tuning and I did get colors but the problem is that it will return to B&W when turning off the Atari and switching it back on.

repetto74 Posted September 10, 2017 Author Share Posted September 10, 2017 So I have disassembled the unit. I have read that first thing to do is to turn the pot to fine tune colors. The pot is the white one (regulated resistor) or the red coil in the middle? Quote Link to comment Share on other sites More sharing options...
repetto74 Posted September 10, 2017 Author Share Posted September 10, 2017 Ok looks sorted out now. I had cleaned the unit, added some solder on the swiches solder joints. Now I do have a B&W image for a few seconds then back to color..weird. Anyway I am waiting for the AV composite pad modification to give this machine a video boost!
