    • I'd be happy to have a look at some of them but the postage to and from Aussie land will be expensive and long.

      Maybe pick a couple to start with, post some pictures and info and see if people can help if you're interested in learning how to repair these yourself.

      I can say from a quick look through your list there are a few I can identify likely faults on:

      CPS1 are most likely bad A or C custom and are unlikely to be repairable unfortunately.

      War Gods will be a bad HDD or CPU will need a reflow, or both. There is an effort at the moment to clone the drives.

      Tekken 2 and 3 will have bad or missing caps on the top board.

      Asterix is a Konami board, most common faults on these are bad mask ROMs, loose customs, bad customs or Fujitsu logic faults.

      Shinobi and Crackdown have suicide batteries that may now be dead. Crackdown can be converted into S24 multi but as far as I'm aware there's no way to restore the original functionality. Shinobi is a simple install of a decrypted ROM if suicided.

      Yes there is now: you can restore the keys in the FD1094 module.

      The main issue here is for most games, once you've paid for shipping back and forth plus parts plus labour it costs you more than a new fully working board.
      And I'm not even talking about bootlegs.
      Looking for:
      - faulty Space Harrier or Enduro Racer
      - Sega Mega-CD 1 power board
      - Super Nintendo CPU (3 needed)

    • Here's some tips when starting to learn how to repair boards (I'm still learning myself).

      1. Firstly, read these articles on AO, they give you the jist of what's involved: wiki.arcadeotaku.com/w/Game_Board_Repair

      2. Get the necessary tools and get familiar and competent with how to use those tools -- for the board repairs you've listed above, at the very least, you be needing a soldering iron, desoldering gun, multimeter, EPROM burner, logic probe, wick, solder, tweezers, cutters, etc. Here are some threads on this forum with some good recommendations and discussion:

      Best, low cost, programmer for most arcade hobbyists to have???
      I need a new soldering iron
      Beginner Recommendations: Hot Air Gun / SMD Rework
      Preferred / Recommended Solder Wire?
      Thoughts on this beginner's soldering kit?
      Oscilloscope for beginner question

      3. Before asking how to repair, it's worth searching the forum, google and other places for repair logs related to the board you're working on. Here's a few places to start you off reading:

      arcadefixer.blogspot.com/
      jammarcade.net/pcb-repair-logs/
      wiki.arcadeotaku.com/w/Category:Repair_Logs
      mikesarcade.com/arcade/repairs/
      newlifegames.net/nlg/index.php?action=forum#5
      aussiearcade.com/forum/arcade/…-and-monitor-repair-logs/

      4. Compare your ROM chips against MAME by dumping your chips and using this tool: romident.coinopflorida.com/ -- If they don't match, they're either dead or you have an undumped version. If they don't compare, try burning the MAME set onto some blank chips and see if that fixes things. This is usually the first step I would advise if there isn't anything visibly wrong with the board.

      Good luck, there's a lot of great people on here who can always help out and I hope this helps you out somehow.
      Multis: CPS-1, CPS-2, CPS-3, F3, S16, ST-V, MVS, AES, M72, Crystal System, G-Net, Naomi, TTX2

    • My process is generally:
      1. boot up the board and verify voltages. identify what it's doing wrong so you have a base line, try flexing the board slightly, wiggling the edge connector, putting pressure on SMD and socketed chips and see if any of these cause a change in behavior. if there is no sound play around with the volume knob, and see if there is at least an amplifier "buzz", touch the pins of the amp chip and see if it amplifies the interference from your finger. If there are no signs of life at all see if it will boot in to test mode by holding the test button down during boot, or if there is a reset button if it will do a warm reset.

      2. inspect the board, look for any faults: scratches that could have damaged traces, cold solder joints, missing stickers over EPROM windows, dirty edge connector, battery or capacitor damage, rust or other oxidation, cold solder joints. A lot of these things may be super minor so if anything is even slightly suspect or has a hint of not being perfect... investigate it.

      3a. if no overtly obvious faults are there then I just cover the basics, use compressed air to blow off any lose dust, reseat any socketed chip and inspect the pins for dirt or oxidation, and I'll clean the edge connector whether it needs it or not (I use liquid deoxit and a nylon scratch pen to clean edge connectors). I'll always do this no matter what.

      3b. If you did find some suspect items then investigate those further, I'll reflow any suspect solder joints, verify continuity across any potentially damaged traces, replace any obviously damaged caps and clean up any corrosion damage and further access those areas. If eproms are missing window stickers then put a new sticker on then dump the eprom and verify it against MAME.

      4. repeat step 1 and re-access if there is any improvement. If not then try to determine where the fault is: bad graphics? no video output? bad audio? no audio output? unresponsive controls? no boot at all? game runs but with bugs? Search to see if others have had similar issues and see if you can find repair logs for that game that mention similar faults, see if there are schematics available, then start using testing equipment to test the chips in that area.

      Generally speaking I'd say 75% of the time I've been able to fix PCBs just in steps 1-3. I can't even tell you how may PCBs I bought non-working that the only thing wrong with it was a dirty edge connector that didn't even look dirty.

    • I'd like to say that the amount of information in this thread so far is excellent! I'm familiar with the low hanging fruit (reflowing, patching traces etc.) and it's done me well so far over the years, but I've been looking at a stubborn Taito F3 that just cycles a single color screen and have no idea where to start in regards to probing and expected voltages at various parts of the board, since I've been lucky enough to never have to haha.

      Repair logs are excellent if you're having a problem someone else has had but it can only take you so far, and lately I've been looking for good sources of knowledge on the general hows and whys on board repair, so I sincerely appreciate when people take the time to explain their processes and link to helpful threads!

      So now I'm confused. Were you working with a repairer who quit? Or do you subcontract the repairs?
