    Neo Geo AES , some lines on TV on bios screen halp !

    hi members , i just got this AES and it seems to have a problem i will post a video below. When cold booting a Cart i get some weird lines on the left of my CRT TV. Interestingly if i press reset on the AES the problem isn't there. Seems to be from cold booting only.

    I found this problem with a AES Cart so i tried 2 MVS Carts with my Daedalus converter , only 1 of the 2 games did it.

    All games tested work just fine no GFX glitches and no sound problems.

    btw this AES has never been opened before......

    thoughts ?

    hi again , can you tell me more about ' sync unstable(dirty) '. I'm thinking of maybe getting a partial refund and keeping this AES and trying to fix it. If the sync problem is a really tough fix i might go for a full refund , also are Video Rams still available to buy ?

    i have re-upped a updated video which is much easier to see the problem.............it happens in both RGB and Composite

    If its the sync I would suspect it just needs a recap. You could try swapping out the 100uF cap on the sync for a new low ESR 470uF and see if that fixes it.
    My YouTube channel contains some MVS repairs and stuff:-
