Commordore 64 character color cycling

I know following up your own request is kinda taboo, but I should have shared more information... I am guessing that the problem is with the Color RAM (SRAM) in slot U6. This model of C64 has socketed components, but I am not sure U6 is one of these. The other possible issue is PLA U17. As the problem never goes away, perhaps it is more than this. Is there a good vendor to get replacements this late in the game?

The system operates fine, except displayed fonts cycle through the color palette. If you remember the old atari 2600 game "Adventure" its behaves like the chalice does, every second or so changing colors. I haven't started probing the system at all, and although I can use a soldering iron, my troubleshooting skills are pretty rusty. I was considering this a good project for a refresher. Sound doable, or is it likely I'll be looking to replace lots of components on the board? Kevin
