Also try using some pressure underneath the small interconnect PCB and the multi boards to push it into place. Ensure a snug and flat fit for all three boards and definitely make sure your CPS-2 A/B are very firmly connected.
Your picture 20210427_194006.jpg. Can you pull from the multi PCB up a bit towards the interconnect PCB. Are you sure that they make proper contact?
Are you using the key injection cable? Which model is your B Board? -3 or -4 ? Can you try romsets that have the key 0xFFFFFFF WITHOUT the cable attached? Does it work now?
Please let us know. Thanks.
I would but i don't have a programmer. If i have damaged it can i send for repair ?If you dont want to wait for the infinikey to arrive, try using the program roms of the versions created by Team Avalaunch or Phoenix. They will work without battery.
He said that he wanted to revert back to Eproms to check that the A and B boards are working OK.You don’t need a programmer. Just disconnect the key writing wire and update the files on your SD card with the decrypted set.
Also short the EXC5.
Got the new multikit today. Can't say I had much success.
I set aside two 93646B-7 boards to try (MSHvSF US and MVC1 JP) as my sacrifice boards. Both had been modified with the Inifikey prior successfully.
I tried the MSHvSF board first. I removed all chips. I removed the infinikey. I installed the three PCBs (I noted mini connect has an up arrow now instead of the RU symbol. I assumed Upwards was the correct direction). I installed the CN9 cable (the one that comes packaged makes it VERY difficult to put on the wrong way, which is a good thing). I installed ribbon cable and connected to LCD. I formatted SD card provided to Fat32 and put the test roms on them.
Upon bootup, I received a black screen, no LCD visual. A green light on the board.
I referred to instructions, which indicated My key writing wires may be installed incorrectly... I double checked both connections. I even tried to "force" doing it the wrong way, but the way the harnesses are molded it makes it impossible.
Next I checked interconnect board... perhaps it wasn't AS SNUG as it could have been, so I really smushed it as tight as possible. No luck there.
"...Key writing wires were shorted to another component on Multi Kit?" I didn't know how to test that. Instead, I did the following:
Okay... so now I tried this on board #2 (MVC1). Ran through all the same tests and diagnostics, Removed an reinstalled components. Nothing.
- Removed all components and reinserted. No luck
- Tested A board with another B board (unmodded). Success.
- Removed and reinserted components again, added clamps to A board and screwed in shell.... no luck.
- Removed SD card, turned on jamma. No luck. Removed Multi kit from B board, used jamma (to reset) then reinstalled multikit and used jamma. No luck.
- Tried shorting EXC5 several times. One time I held it for 2 minutes.
- Upped voltage to 5.1v per djsheep's recommendation (Previously had it at exactly 5.0). No luck.
- Re-added Inifikey. No luck.
- Re-added inifikey with no code. No Luck.
- Re-added original chips and removed multikit. Re-added Infinikey with encryption code. Success!
- Reformatted SD card. Used Darksoft CPS2 2020-05-24 pack. No dice. (I didn't try the unpatched pack, although since I can't get it the LCD to turn on I am unsure if that will make a difference).
- Per someone's post with a similar problem, I tried "washing" all contacts with alcohol. Certainly made everything cleaner looking... but still no luck.
- Re-did back of CN9 contact points (where infinikey was soldered previously) to be clean with no impurities. Nothing.
I'm stuck. Dunno what else to do. Pretty bummed.
Pics attached. Let me know if there is any more detail you need from me.
Sorry, I should have said this as well - - yes, I keep turning the pot at every test to see if any change occurs, nothing. There doesn't appear to be any illumination at all.Does anything show on the lcd when you adjust the lcd contrast pot on the multi?
I can't say I tried hitting the load button each time, but a few times, Yes. Still nothing. I guess I can try a pre-patched game to rule that out.What @Mitsurugi-w said, is there any illumination or change on the LCD panel whatsoever when applying power? You can change the contrast level on the main Multi board with the little potentiometer.
Also worth trying hitting the bottom load button on the LCD to see if that does anything (loads a game)
If none of this is successful, I would guess it’s a faulty LCD or LCD cable. Do you have another Darksoft multi with a LCD selector by chance?
We’ll get you sorted out and major props for actually trying all the troubleshooting steps available before posting
Are you suggesting trying a board that is LIVE? (battery still operational) or a suicided non-injected board?^THAT^
Also remember the troubleshoot thread. Its key to start always testing games that dont need key injection so you discard this as the source of the problem.
You may be right about the cable... the fed-wire "seems" to be fed backwards into the clamp instead of forward. The wire came that way. Think that would have anything to do with it?@Darksoft was saying to use the unencrypted set of ROMs, but it’s not really useful if the selector isn’t working.
I’d say your issue lies with the LCD selector, cable or the connector on the PCB itself. Did you have another selector by chance? If not, maybe there’s someone here on the forums from Philly who can help you out.
When turning on the multi and looking at the selector screen is there any form of movement on the screen or life signs at all upon powering on? Please try this test with the pot on either end of its range and also roughy in the middle. If there’s none I would suggest trying another cable first, then selector.
