AtariBrian #1 Posted July 2, 2017 I am just curious what people think is the issue here . I assume it is the video chip ? This is my friends av modded Colecovision . Tried two different power supplies so that is not the issue . Quote Share this post Link to post Share on other sites
Pixelboy #2 Posted July 2, 2017 I've seen graphic glitches like this in the past where the culprit was the power switch. Not sure if that's the case here though. Quote Share this post Link to post Share on other sites

+-^CrossBow^- #4 Posted July 2, 2017 Very likely to be a failing ram chip. Very common on the CV. I would suggest doing the +5 vram upgrade, but that isn't a mod for the delicate of heart.https://console5.com/store/colecovision-5v-memory-upgrade-kit.html Quote Share this post Link to post Share on other sites
