Title: Giant arc from ? to k7000 chassis (with video)
Post by: robbbby on July 15, 2021, 08:33:16 pm: So quite a few years ago I bought a massive rebuild kit for my k7000, it included damn near every part including fly back.
After rebuild, machine got minimal use, sat for years until I recently decided to get it running again on new software.
Everything was fine until today. I’d hear an occasional tick/arc sound, monitor would sort of jump or move every time I heard the noise. I tried looking behind with monitor on to see if I could spot the issue but I couldn’t pinpoint what was happening, until now.
Suddenly it went from the occasional tick to full blown OH CRAP PULL THE POWER CORD.

I plugged it back in just so that I could take this video and see what was going on.

Can anyone make out where it’s coming from or what problem might be? Looks like it’s arcing from behind fly back to the chassis.

I always wondered how exactly that cage served its purpose in regard to being a safety measure.

Your video illustrates that pretty clearly!

Glad you didn't get blasted and appreciate you sharing the video.

And as always thanks Ken for sharing monitor wisdom.

Thanks for confirming my suspicions Ken.
The parts were all purchased from arcadecup in 2016.

Is there a better place to order flybacks from?

Thanks

Post by: MKFan4Life on August 19, 2021, 12:33:03 am: Nice arc, but I don't know what depresses me more... that I can't save it to my favorites because it's marked as made for kids, and YouTube doesn't allow adding vids to favorites that are marked that way, or that YouTube forced me to watch a 5 second ad for a 6 second video clip. Lol!

Fix that thing before ya fry some small rodent!
;D

Post by: MKFan4Life on August 19, 2021, 09:56:58 pm: I'll check it out. Hopefully it's not one of those apps that needs permissions like:
1. Permission to access your contacts (Why?)
2. Permission to access your camera (To take pics of you in the bathroom?)
3. Permission to access your significant other (Uh...)

Just kidding... maybe.
