Hello Everyone
This is the first time visiting this forum for me, I hope i didn't missed any presentations topic or anything like that
Anyway, I need the point of view of experts, I played all my cards from my side.
So, I have an AES for almost 20 years, about 4 years ago, it stopped working with this symptom:
(it seems that youtube integration doesn't work : https://youtu.be/s9PA5KkYumk
The boot jingle loops, and as you can see, the graphics are totaly out of sync.
Without game, i got this :
Links to video : https://youtu.be/_aRLw9szLtM
Pretty much the same.
4 years ago, i couldnt do anything, had not any material to work with chips, nowaday I have more to work with, and I got myself the very good Neo Diag Bios, which I installed, and got this results :
Link to video : https://youtu.be/UDZL3gGtykg
I could see that it was trying to tell me something, but the console is not able to display anything properly, so I had to go further, and install the M1 chip in a cartridge
The sound code that it make is clearly 001100 :
So according to the official Neo Bios site means :
A quick look at the possible solutions give this :
I checked all the tracks that are listed here, all good (the board is very clean and looks almost like new)
I might send my AES to a professional repaire shop, but maybe someone here already had that kind of exact symptoms and error codes?
Thanks anyway for reading, regards

So according to the official Neo Bios site means :
Z80<->68k COMM. ERROR (DATA) 001100
A quick look at the possible solutions give this :
Z80 isn't receiving the expected data from the 68k communication I/O port. Most likely an issue with the Z80 data bus or control signal trace to the chips that control the port (NEO-C1, NEO-D0).
Z80 D0~D7 → NEO-C1 SD0~SD7
Z80 IORQ (20) → NEO-D0 IORQ (37)
NEO-D0 SDZ80R (41), SDZ80W (43) → NEO-C1 SDZ80R (84), SDZ80W (85)
