does this chassis require an isolation transformer and are you using one?
The chassis is a generic one from China, as far as I can tell. Can't find any info online by searching model numbers. The cab did not have a isolation transformer when it arrived. It also didn't have a ground wire on the incoming power cord. It had a janky-looking wiring setup, that could have been daisy-chained off another cab (had an outlet on the back in addition to the power cable to plug in).
The monitor had been running fine for weeks prior. I'm going to pull it out and see if something got bumped or snapped when I reoriented the cab. I opened a different thread for troubleshooting the monitor - https://www.arcade-projects.com/threads/ok-baby-no-picture-and-chassis-is-a-mystery.27476/
[Edit: Chassis has been identified as a Yatta Model 988]
