I could use some advice.
A few months back, I opted to do a composite mod on my 4-switch Woody. Since I didn't feel like hunting down some perfboard and didn't have the right resistor values on-hand, I just picked up one of these: http://www.ebay.com/itm/Atari-2600-A-V-Composite-RCA-Audio-Video-Mod-Upgrade-Kit-Fully-Assembled-/272271974442?hash=item3f64aca02a:g:xssAAOSwHoFXtCcF
I clipped the resistor between "Ground Out" and "Video Out" since I'd read that it only succeeds in dimming the display a little.
The install was simple and there's no static, the sound is great, and the rest of the restoration work on this console made it look like new.
But there are still some things that bug me. For one, the colors look a bit strange. I've used the color pot to tune this as best I can (using the colors on Centipede and Barnstorming as a guide), but some games are simply not looking like I would expect them to - some of the dark colors seem off, and the whole image is more dim than I'd like. There's also the problem of sharpness in the details. Compared to the output on my 7800 (also AV modded), many of the same games just look like garbage, though are playable in any case.
Normally I would be playing both systems exclusively on a CRT television, but the one I have is finally giving up the ghost, so I'm stuck using an LCD TV for now. I understand that, regardless of the mods you do, an LCD is seldom kind to consoles of this vintage. Suffice it to say, I'm not expecting miracles here.
So, now that I've laid all that out, is there anything I can do to improve the picture further? My first thought was that this machine is showing its age and probably just needs some capacitors replaced or something, but I don't (yet) have the technical expertise to say that with any certainty. Any help would be appreciated, and I can supply pictures if needed.
