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?

VRAM failure

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.

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.
