Neo Geo AES Graphic Problems

Hello Friends,

i have a Problem with my Neo Geo AES Console. Today i want to play with my Console but all Games have in the Intro Points and Lines on the Screen. When the Console starting without a Casette than th Screen is blus. I think this is correct. The most Problem are with the Intros, the Games have not so many Problems. I hope anybody can help me with the Problem.
Thanks and Reagards from Vienna.

I'm assuming this is a 1st gen system? Check the soldering on the LSPC-A0.

That, and try pressing down on PRO-C0 and PRO-B0, to see if the dot pattern changes.
Not long ago HPMAN showed me a very similar problem he had with a 1st gen. After checking connections between the video chips, we guessed it could only be an internal fault. Replacing PRO-B0 solved the issue.

Hope that dying RAM in PRO- chips isn't becoming common...

There's RAM in one of them?!?!

Yeah the line buffers are split in both (can't remember how), the sprite pixels are rendered in them.
In second gen systems they're all in NEO-B1. On the Alpha68k they were made of a bunch of fast RAM chips that could be replaced
