Got this monitor in with symptoms I don't come across often. There's no
picture, and the HV while present, only measures about 8KV, I'm guessing
this is the reason for no pic. It's quite difficult to get in and measure
waveforms with the monitor operating, is the flyback a common failure in
these? It uses a separate MOSFET to drive the HV, I tried a ring test on the
flyback between ground and pin 1 which I *think* is the drive pin and only
get 2 lights on the tester, I'm not sure however if this applies to this
sort of setup. Anything else I should look out for on this thing? Seems to
be a pretty decent 21" trinitron monitor.
