It's been playing perfectly fine, I've had a Mistercade in it for the past few days, zero issue.
I turned it on remotely this evening (smart plug app) so I wasn't in the room when the cabs were switched on. However, nothing had been changed, touched, moved, bumped since it was working perfectly fine yesterday.
The Windy 2 and the U4 both run from the same 2 socket step down (Airlink), and the U4 is on and working fine.
I came into the room a few minutes after the cabs had been switched on and the windy marquee light was on, I could hear the fans spinning, but the screen was blank. I opened the front and could see that there was power to the MiSTercade. I could also hear a 'chirping' sound coming from the chassis.
I turned it off, double checked the connections, all seemed fine. Turned it back on, there is power but the screen is completely black and the chassis still chirps.
I pulled it out to have a better look, and changed the PCB. Same issue, power, lights, dead screen and chirping.
I obviously know bugger all about what does what on a chassis, so I've taken a brief video and you can hear that the chirping seems to be coming from an area on the chassis towards the front of the cab.
Any ideas?
Edit: basic googling suggests it's a switching power supply issue. Likely a high voltage capacitor?! That's good, right? As in, fairly easily rectified??
Edit 2: Or the hot, or the flyback. I'm giving up on trying to self diagnose. Even if I do stumble across the right answer I still won't be able to do anything about it
