  1. SNES / SFC SHVC-CPU-001 2-chip RGB filter mod video fix

    NOTE: this is untested by me, use at your own risk. I hope to get around to testing soon.

    A little while ago someone posted a link to a Super Famicom/SNES video filter mod I thought I’d try my...
  2. PC Engine PCBs - RGB amp, Hucard, Controller board.

    I’ve been playing around in the EasyEDA online PCB designer for a while, and wanted to share some designs in case anyone can use them. No warranty is given and no claim is made that these are fit for...

    That video amp you linked to is not a j-pac, be aware. And it, or an actual j-pac, won't get you 15kHz video, which i'm assuming is what the CRT will need. If so, try this guide.

    You probably will...

    Yer audio and video both missing probably means the power supply in the cab is dicky.

    Go back to my post above, and if that doesn't help, let's talk video sources - what are you plugging into the chassis, an original old game board? A multiboard? Do you have any other video sources...

    Still, i'd give them a look if i was nearby.

    Hmmm, IIRC the KZ-20EN is the same thing as the Sega MC-2000S. That's really the chassis designation, so there would normally be another sticker on the tube, maybe from Mitsubishi or Hitachi. If...

    A true jamma board is oing to be easiest, and if in good shape most reliable, but you only get one game. A multiboard is about as easy, and after that an rPi is more work but gives a better result...

    I think MarkOZLAD had a 59cm tube recently...? He's in Newcastle though.

    Perspex diffuser? Is that the same thing as the Fresnel Lens? That's the corrugated sheet to help spread the light? I know jack-all about RP sets though, so i wouldn't trust myself to be right. Was...

    There's a distortion correct pot on the D-board accessible from the back, which will probably affect this. That and the H-sync pot are the ones to try first. Be aware that adjusting for one image at...

    It is slightly weird that the 2130 doesn't show reflection when it's meant to take 75R video. High quality arcade monitors don't normally care, but the PVM should.

    Still, I'm glad I was wrong and...

    The 75R terminations are the first components inside the PVM for the R, G & B lines - at least according to the service manual. If other consoles are working fine and don't get reflection whether at...

    Ahhh, yup, ok. Hmmm, it's definitely signal reflection, but after telling you to check your cables, it's not easy to diagnose. If you're on a pal GC, using RGB, where did the cables come from, and do...

    Presuming the monitor still works fine with the Jackie Chan board... I wouldn't imagine it would be economical to repair an XXX-in-1 with those symptoms, but i'm not expert. The alternatives are, a...
