TBH, I find it odd that the crosshatch would show up on the NeoSD, IME power issues should result in garbled boot/graphics/instability...

Yeah, those holes look very suspect. You should test the traces off the ZMC2 for continuity with a multimeter and patch any broken traces.

you can measure the voltage with a simple multi meter, below 4.9V on the ICs and you can expect problems, epspecially with a NeoSD which...

Take good detail photos of the battery and the area around it, and yes, the ZMC2 that @BIG BEAR mentioned is in that spot as well...

Congrats on getting this old beauty :) This is a NEO-AES, not a 3-1, its the first revision one released, there is no "RGB mod" for it...

Matrimelee is one of the games I use for testing Neo Geo with a 161-in-1 cart (or currently a NeoSD while I have it here), the other one...

Wouldn't worry about the passives as much as the chips. Datasheets usually have an absolute max rating table and the THS7374 part you...

Doubt the stuff here will help fix the watchdog. Watchdog means 68k won't boot or is crashing and audio/video section parts probably...

Hi all, just got a NeoSD MVS module, first one ever. I bought it used with a 32GiB SD card, the whole MVS library is supposed to be on...

Actually it was an issue with the Jamma Harness Connector, after chasing my own tail, I noticed that it way worse when I moved the...

I have a MV4 here for repair, still waiting for the power supply to run it, the ones I have here aren't strong enough it also had the...

I use both a 1991 Loewe CRT and an OSSC with a 55 inch Dell Monitor. Thank you, I should have tried that, but I'd need to built DFOs as...

Are you using a CRT? I found that the 24.00Mhz crystal oddly has a noisier image on modern displays. Verified on AES and MVS with...

turns out that there is a jumper for the CXA1145P for PAL or NTSC as well, probably for the composite video I didn't feel like tuning...

Yeah, the weird thing is, I had AES3-5 with a nearly perfect picture, and now this one is quite off. I'm doing the same thing to all...
