[rescue] ZX framebuffer

[silcreval]

Well despite a lot of effort, I have to declare my ZX framebuffer flakey. About half the time it comes up fine and the rest of the time it goes into a state where the screen is filled with lines.

I've spent quite a bit of time on this board, and replaced all the caps, desoldered the connectors and checked them, etc.

However it looks like its not going to be an easy fix.

I did buy another board on eBay, but thats even worse :/

Has anyone had experience with these cards?
