    Pioneer LaserActive Repairs

    Cool to see some Laseractive love on here. I documented a repair on my website a while back and used to own 3x of them back when they were cheap. Such a cool piece of tech. But no fun to work on nowadays.

I just modified it for S-video...BUT it hates being tated :( It doesn't appear to have a degaussing coil inside, which is usually fine. But when I turn it sideways to play shmups the thing has like a rolling degauss problem...its...

    Trouble with my Neo Geos :(

    somehow I can't get any luck with getting one fully-working Neo Geo system and a 161 in 1... I have a MV-1 that gives the error message about address 02F00C0. if I press C the games seem to work okay though... Maybe this is just an incompatibility with Uni Bios v2.3? My MV-1B seems to work...

    MV-1B constantly resetting, won't get past radio screen

    I got an MV-1 (not 1B, title is a typo) to repair but I haven't actually come across this issue before. It boots up to the green garbled graphic, goes black and boots up again, repeating indefinitely. Anyone know a good place to start? I inspected traces and looked for leaking battery acid or...

    FREE MV-1B covers

    Stepping up my lasercutting game and made these yesterday. In order to further my capitalistic conquest to rule the world I've decided to give some away. Only asking for cost of shipping in a paper mailer. These are cardboard, so very expensive. I could make acrylic and other fanciness but...

    161-in-1 with NO sound (shocking, I know)

    Got one of these crapola things to try and fix. Double checked 3.3v and 4.2v lines on the board and reflowed the soundchip and some dodgy connectors. cart edge is perfect. Issue remains. Anyone have any ideas? V3 and V4 on the program board get pretty warm....all the other chips of the same...
