Neo-Geo AES graphics corrupted / display issue

[pc741]

I've just got hold of an AES and the graphics are all corrupted.

I've cleaned the carts, I've cleaned the cart slot, checked my cables and when the AES is powered on without a cart inserted I get a blue screen.

Sound is fine.

This is what I get:

Any suggestions at what I'm looking at here, please?

Thanks~

First you want to examine the board and check for bad traces/tracks around the video related components.
