This monitor has been fixed :D Replaced R438, with the Vishay PR02FS0202708KR500 2W 2.7 Ω, fits nicely, and recapped it, but nothing changed, it was good to do it anyways, probably fixed other unseen issues, one of the capacitors had 90ohms ESR! Then I could not make it turn on again, but that...

Recapped the thing (all minus filter) Also took out and tested all the color drive transistors close to the pots 1x A928A Y, 2x A733, 7x C945 - all fine 1N4148 diodes were fine too Replaced the diodes and C945s anyways just in case Found heater resistor was red/red/gold/gold (2.2ohm), but was...

This is more difficult than expected, I can't find 2.7 Ω 1/2w fusible resistors anywhere, tried mouser/digikey, ebay and arcadepartsandrepair. Also I'm not even sure if it is 1/2w or 1w? measures 8.5mm length, 3mm diameter, so it matches a usual 1/2w carbon but that does not guarantee it. Also...

Got it, I won't try the Kortek then, I guess I'll try it in the future with a TV tube+yoke since you mention it's could be a good fit for standard NTSC yoke (measuring inductance before), but that'll be a different topic, thanks!. About the MS8-25 vertical collapse issue, this is what I had...

Hi, I've got a Nanao MS8-25FTB chassis that has vertical collapse, tube is Toshiba A59JMZ193X, yoke readings (not perfect) are: 0.4 ohm / 0.360mh 6.4 ohm / 25.47mh While I'm trying to repair the chassis (difficult), could something worse than odd geometry happen if try the tube with a Kortek...

Hi guys, I really want to have my House of the Dead cabinet working, I've been able to fix the game PCB thinking the monitor wouldn't be that hard, but it is giving me a bunch of issues, I've been able to overcome most, but now I've become stuck. It's a Ducksan CGM-3307E 33', NAP M78JUA069X...

Just found out ArcadeCup has a pic of it with a film capacitor (it is to the right of DY-CON1), so option D should work :)

Very weird, I can't think of anything else more than testing the old srams that have been taken off the board, if they work then they weren't part of the problem, but if any fails then there could be an issue with the soldering of the new ones. If not try find diagnose related components...

What does the boot screen says about the sound system status? any message?

Hi guys, I find myself recapping a Hong Eun MP-29A chassis, chosen the caps myself, everything is going smooth so far, but I have this curious size difference between the old and new only BP capacitor. Even that they have the same voltage rating and capacitance, the old one is much larger than...

Sure they'll be fine, I guess Mouser ran out of stock first

Hi XaryC, yes, I soldered those new faster ISSI ones in the board that I had taken its SRAMs from, it worked perfectly. I don't remember exactly how many bongs the board was doing but I think it's good to try replacing them if you're having that symptom. Also when soldering those I tried using a...

thanks! It was mostly replace ICs around between boards, tedious but with the right equipment is quite doable, the difficult part was to not to give up when not getting the expected results, and keep on going trying to exhaust all possibilities lol

Cancelling this WTB request because I managed to fix my board: https://forums.arcade-museum.com/threads/sega-model-2c-house-of-the-dead-3d-graphics-issues-repair-log.549523/

I've got a HOTD cabinet with too many odd graphical issues (flying polygons/textures) I've tried to fix without success so far, so I'm looking for a spare CPU board to just swap and hopefully solve this issue (Sega Model 2C CRX CPU board) Would need shipping to US Thanks!

Hi there, I am trying to make the PSU of Korean House of the Dead 1 "upright" cabinet work, it almost works, model 400-5306CE-01, exactly like the one from this image: I'm testing the power supply individually before trying it in the cabinet for first time, with a dummy load in the +5v side...

Found them, after some intense reverse image search, they're ELR-12V and ELP-12R And found a better picture https://www.jessewolcott.com/korean-ddr-pad-connector/ Unfortunately they're very hard to get unless purchased by a large amount.

Looking for a spare Namco 54XX custom chip to repair a Xevious board. Original or repro is fine.

Looking for some assistance please with these ones from a Korean DDR cabinet, it didn't come with the cable that connects the cabinet to the dance pads, so I need to build one myself, since also from both sides the connectors are the same gender, but couldn't find what they are. Japanese DDR...

I plan to replace all rams with new ones, just haven't been able to do it yet. I've purchased these, hopefully they are the right fit: GPU: IS42S16100H (512K Words x 16 Bits x 2 Banks) (16-MBIT) - confirmed as good for graphics ram CPU: IS42S16400J (1 Meg Bits x 16 Bits x 4 Banks) (64-MBIT) -...
