Subject: [stella] Helpful info for cleaning your Atari 2600 console From: info@xxxxxxxxxxxxxxx Date: Sun, 18 Apr 2004 11:18:48 -0500 |
Hey everyone, I don't know if this information has made its rounds. I'm not going to attempt a compendium of cleaning information, but here are a few things I discovered while cleaning my 4-switcher that I couldn't find information about online: * Twitchy colors may be the result of a dirty color potentiometer (simple, but not talked about in the context of a noisy picture as far as I could tell). Clean it with electronic contact cleaner (not WD-40!), give it a few spins back and forth, then calibrate it with a game you're familiar with or a color bar generator cart. * I used contact spray on the RCA connection where the RF cable meets the motherboard. * There looks to be two other potentiometers that may be adjusted with a small allen wrench. I didn't touch these and don't know what they do, even after checking the web. Anyone know? * I had removed the metal shield from the top and bottom of the board during cleaning, not realizing exactly how indispensable it was for attaining a clear picture. I had vibrant colors and a still frame from cleaning the color pot and cable connection, but noticed (this is going to sound weird) game-specific noise... almost like ghosting of the game logic across each scanline. When I replaced the shield, the picture was VERY crisp and very colorful. The only artifacts remaining are very faint vertical, but equidistant bands, but they are hardly a distraction. I considered doing a composite mod until I cleaned everything, but there's not much of a need now. -Lee ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
