Received a New Net City cab via freight shipping yesterday from a reputable seller. Monitor was tested fine at 31 kHz before shipping, seller did say it had a dim picture at 15 kHz and would likely need some adjusting. I plugged in the cab and fed it a 15 kHz RGBS signal from my MAME PC (the same signal worked fine on my BVM). It was very dim and almost "zoomed in" and stretched. I opened the control panel, degaussed and began to adjust the contrast when the monitor rapidly began turning itself on and off with no image (just a white "flash" and a clicking sound", and I smelled what I believed to be burning/plastic melting. I unplugged the cab. Now when I power on the cab and try to feed a signal, either 15 or 31, the monitor does not power on (not even a "No Signal"). There are three rapid clicks when I turn it on if it's fed a 15 signal, one click with a 31. Can't get it to display with the MAME PC, Dreamcast via VGA or Xbox 360 via VGA (the MAME PC is confirmed to work with a New Astro City via JPAC).

I have very little experience with CRT repair, testing voltages, etc. so if there are any procedures I should try please explain them as though I am a complete beginner. Do these symptoms point to anything specific that probably failed (Flyback, HOT, etc.) or is the cause easily diagnosable?
Thanks in advance!
