Thanks for letting me know. I'll probably just save up for a proper cable and device. It probably needs a raw unfiltered signal or something. I'm not going to get the kind of circuit that relies on pots, too much work. I do have a few AD725s, but I definitely couldn't get it to work.

I'm using my 1.7 standard minigun and I constructed a cable to connect to a RGB to YPbPr circuit but I'm getting no output. Maybe I'm not supposed to use any caps or resistors in the converter circuit? It will be a while before I actually get a proper SCART cable with OSSC/RetroTink...

Yeah, I'm going to have to order the Neo-Buf parts from a pcb fabricator as furrtek has none for sale. But considering what's going on in China, it will be quite a while before I finally fix this unit.

Yes. It registers 5V on the bottom legs according to the voltmeter. And there was no battery leakage. The board is more or less satisfactory clean. If a backup data error causes this wouldn't the screen be brighter and be more solid like your typical Neo Geo boot sequence? And I installed the...

I bought a junk MVS MV-1A in hopes of an easy repair, but when I turn it on, I get this bizarre screen. I've replaced all the capacitors, cut the 12V leg on that voltage regulator, replaced the smaller 32.768 crystal, and removed the battery. Thank you.

Solved my little problem, I used the wrong size barrel connector with the power adapter. Lights up. Now I have to construct another RGB to Component Video adapter. I've made one for my integrated MVS and it works great. But reading a few pages back where a user bought the RGB to VGA board makes...

Phew I was worried for a bit, so I must have gotten a defective board. Will have to wait for a bit to test tho.

Really foolish question, but you turn on the device by pressing the tact switches right? Not by the slide switch? I finally built a 1.7 Standard but haven't populated a few parts yet, especially the tacts. I wonder if anybody has made a youtube video detailing this device or any revision.

Is there anything I need to do to make the Standard Mini-Gun work on +5V only, like a Neo Geo MV1B or C? I installed most of the components on my pcb except for the tact switches, the molex, and the mini-din connector. When I flip the switch, the light doesn't turn on, and no output. Thank you.
