I have done bivert mods on two gameboys and both of them have the same issue. Only two of the 4 shades of grey will display.

Also running my finger around the bivert board while it's booted causes graphical glitches. It seems like it's maybe a problem with some connections somewhere, but I'm not sure where to check. Any help would be appreciated!
Here's some pictures:
This is what I get:
