I recently got myself an AES, turns out to be 3-3 board.
I was horrified with the quality of the RGB out compared to my CMVS so I followed the Bypass mod as in this link http://www.neo-geo.com/forums/showthread.php?158147-RGB-bypassing-a-NEO-AES3-4&highlight=aes3

This has had a significant improvment in picture quality but I can see scrolling noise in the background as seen in the pics here

I found that changing from a switched mode Psu to a transformer based one helped alot but im still seeing the noise and its very annoying.

I was not able to find much info on the AES3-3 board so I'm not sure if the RGB bypass was needed. I removed all the components carefully so it can be restored if needed.

I'm also using a euro scart lead with a lead in the headphone socket for Audio.

From reading old threads the conclusion was to try another TV, but I thought maybe there had been a newer method that fixes it and I dont see this issue with other consoles or from MVS.

Thanks in advance :blow_top:

Try using sync from pin 10 instead of Pin 11.

After trying many many things to cure this, it turned out to be the Power Supply, it works fine with an old Super Famicom Psu. was about the 5th Psu I tried.!!
