This board had a bunch of corrosion along the jamma edge. It was missing the color blue, I was able to fix it by patching the trace that leads to pin 13 of the jamma edge. It does have another issue though, the board test fine in the post but the sound does not work. Anytime a sound tries to pay...

Got a STV sent to me for black screen and stuck player 2 inputs, the thing was filthy so I gave it the usual bath and reflowing the SH2 got the game to boot fine. Now for the stuck inputs I am suspecting the custom 315-5649. Anyone know about his chip? View...

Went to Pensilvannia yesterday to work on a versus city. Chassis 2 had runaway brightness issues, player 1 was functional but I decided to recap and reflow as well. I figured since I was there already I might as well. Some pictures of the issue and a link to the Twitter post of the repair job...

This one was working until the owner was curious about the unused leg on the watchdog chip being up and soldered it back down, the board went on a reset loop. When he went to de-solder the leg and put it back up he unfortunately broke the pin. Unbeknownst to him this pad routed a trace from the...

Got this from a friend and been working at it slowly for a while. The sound starts rough with noise and eventually dies out and comes back in and out. This is what I did so far guys, changed the pot, changed the electrolytic caps, changed the tantalum 4.7ufs, changed the 640khz resonators which...

Got this new generation cart I was converting for a friend that won't boot. At first it would do nothing, after I reflowed the CPU it seemed like it was trying to boot but would reset. Now I had ordered the two nand gate chips, I received one and swapped it and now it doesn't reset but just...

A friend asked me online how to deal with graphical issues on his board and I gave him more or less what he had to check. He tried replacing the on board ram and ended up busting a few pads. He tried patching it and then gave up and sent it to his other friend. His other friend was unable to get...

Big Blue at my local arcade lost the color red after going over the chassis and changing both red transistors the problem persisted. I checked the tube and it had a bad red gun that not even rejuvenation brought back. Had a sansui consumer set laying around with an Orion tube that was in good...

Went to my buddy's dojo yesterday to fix a previous patch work on his pd1843 neckboard that had lost the color green. When the chassis was originally shipped to him the neck board cracked slightly and he had someone patch it. I went over the patch work and decided to tidy it up. After tidying it...

Had a Naomi inside a big blue at my local arcade for over a year running Marvel 2. Out of nowhere last Saturday we got this half image. So far I tried a different Naomi board, different Capcom io, different monitor chassis remote board. It all showed the same half image, I also messed with the...

Got a CPS3 missing blue from @paris_green . I after doing backwards continuity check from the jamma edge and finding no broken traces. I went ahead and replaced 8D CU3383 from a donor board and still had no blue, at this point I knew it was the output side of the dac. Went ahead and took a dac...

Got a 4 slot from a friend that was not working, I patched a trace under the battery and got it to boot. Only issue is I get sound out of only slot 1 and 3 but not slot 2 and 4. I already cleaned the slots and inspected the board for for broken traces and found none aside the one under the battery.

Blast city at Brooklyn Arcade was maxing out at 4.77V , making the naomi 2 in it freeze. Last night I took it apart cleaned and recapped it and the sound amp. Surprisingly after this the 5v jumped up to 5.21, I brought it back down to 5.08 and let it run for hours with no issues.

My friend's arcade, https://x.com/ArcadeBrooklyn?t=XricFftS9LcnTML8mQ5q6g&s=09 Had receives a versus city last Saturday and player 1 monitor was shrinking horizontally. Took the chassis out last night and found tons of bad pads and shitty patch work. Was able to redo all of it and get it back...

Installed unibios and an RCA stereo out for a buddy of mines. The versus harness for his Astro City cabs only has RCA in for audio and not jamma. He was getting no sound while playing his mv1c, so he sent on my way for moddingm

Someone saw my post about the previous cps3 ppu pin repair and sent me theirs. Seems their graphical issues were similar. Some pins were bent, some were floating. I reflowed and straightened the pins.

Friend from Mexico gave me a cps3 that had corrupted graphics. Turned out to be a bunch of pins that were bent and shorting out.

This is in a windy 2 given to me by a friend, the cab was non working I believe maybe a part of that big buy a few years ago. I cleaned it up as best as I could and tried turning it on and got a thin blue line down the middle vertical collapse. I went a head took the chassis out, it had a lot...

A friends MSH V SF board was showing vertical bars in the video, when I took it off the B board the A board had a broken pin. I was able to take the pin from one of my broken parts board and use it to fix the problem.

One of the screws on my windy 2 rusted off so I ended up swapping both locks. I was lucky to still have both tangs. I also installed the PCB door kill switch bypass on one of my buddies blast city.
