Greg2600 Posted December 30, 2017 Share Posted December 30, 2017 Sad to say that my CV is on the fritz. Seems like a RAM and/or VDP issue. Normally I'd just look for a working replacement, but this one was AV-modded by Yurkie so I have to get it repaired. I have tried multiple carts. Thoughts on the issue?

Kiwi Posted December 31, 2017 Share Posted December 31, 2017 (edited) Suggestion: If it booting up cold, I would let unit warm up for awhile as the capacitors and other components, TMS9918A, are old. Pacman Collection looks better then the SD menu screen. Knightmare would be my suggestion for a game to let it warm up. It has a game play demo as it would load data to VRAM and cycle from the title to the game every minute. And make sure that the power plug is firmly in the Colecovision.

Greg2600 Posted January 2, 2018 Author Share Posted January 2, 2018 Well, I straightened the power supply's wire out, and that seemed to fix the issues. Worked for 2 days straight, so hopefully stays that way. Quote Link to comment Share on other sites More sharing options...
