So heres a story about my adventure with Arcade CRT issues. A cautionary tale
.
So I bought this cabinet a few months ago, it did not seem to have any issues
It is an Atomiswave SD Candy Cabinet, manufactured in 2003. According to the Arcade Otaku Wiki it has a Wei-ya M3192D Monitor. Based on a bunch of digging, people have reported major issues with the Monitor it comes with since 2008 (That I can find). The consensus is that it was made with shitty cheap components.
Im still fairly new to Arcade Hardware, I don't have a ton of electronics experience in terms of repairing these sorts of issues so I needed to find help. I originally took the machine to a place in El Monte, CA called Vics Videogames. They claimed to have fixed the issue, it certainly powered on at the shop after it sat with him for a month so I didn't question it. This is after I called once a week for that month asking where it was at and I got a lot of We had to help other customers, they need theirs repaired now before yours. Im pretty patient, but after a month of hearing the same line with no progress it was getting old. By this point I thought it was screwed completely, I just wanted confirmation so I could start looking for a replacement. 5 minutes after getting it home and plugged in, zaaaaap it was dead. There was no literal zap
it just wobbled on screen for a bit and went dark. Kind of like the end of Terminator 2, except to the sound of MvC2s Jazz intro music. My other cabs are connected to the same outlet and are fine so I was pretty safe to assume it wasn't my wall outlet killing it, at least on its own. The guys at the place said they had to double on diodes because they kept frying after a short time being on. I was fed up with the bullshit, no more business there from me.
I was about ready to sell the cab, which was sad because I got it at a good deal and I have my MvC2 setup in it. I thought id do a bit more digging. I found P&L Videogames in Baldwin Park, CA but unlike Vic's place, P&L had some community backup on posts on NEO-GEO.com forums and some other random Arcade focused forums. I had only found Vics on Yelp, and thats it. I called the place up and asked what they needed from me to get this thing repaired. Now to be clear the monitor has NO burn in whatsoever and had a beautiful picture. Ive filmed it a few times, like this video
https://youtu.be/r9OW1YgqcUE, where it was up and running with no issue. They told me to only bring in the Chassis.
Yikes!
Ive never pulled a Chassis before, and I wasnt feeling very confident. My father who has a lot more experience with this sort of thing offered to help. Partly because I had bought him a cab and his monitor was failing as well, but for other reasons. Being that this cab uses a flat tube monitor that runs all three arcade resolutions it has a lot more cables to unplug because of its complexity. It also doesn't exactly help that the control panel is not on the chassis board and is connected via various wires to a sub board. After taking a LOT of pictures, we pulled the Chassis with some help from Johns arcade video tutorial. After looking at the Chassis carefully, I couldn't find any modifications to the board whatsoever! Where the fuck were these so called doubled up diodes? It doesn't look like anyone but a machine has soldered anything on this board since it was assembled.
I took the Chassis to P&L and within 3 days (today) they called me back with it repaired. The guy told me Whoever worked on this before fucked it up. In the end it required a Cap job, and a new Flyback plus whatever things he had to fix that were modified. Based on my own reading the flyback issue might have texplained the clicking noise the monitor was making after it died and might have explained the over voltage issue where it kept frying components. I thought the clicking might be the monitor having trouble finding the right resolution.
Now, I just received it repaired from P&L, and I have not installed it back into the cab yet. Im feeling confident based on the fact I can see the modifications (New caps, flyback) changes to the board itself. Also, unlike Vics place, P&L seem to really only work on Monitors. They have monitors galore and this was a monitor issue.
I will be reinstalling this thing on Friday for a hopefully final determination if its going to work or not. I have come to the conclusion if not, I might just replace the monitor entirely with a new one that Suzo Harp sells. Looks like it might still be more Wei-ya rebranded crap, but it will at least be working. If anyone is interested I will update this on Saturday when and if its up and running
..or not.
