The HV never energizes and no other sounds are audible from within. Inspecting the boards revealed no burned, blown, bulged, or otherwise visibly defective components.
I used to know all the standby LED codes...Googling suggests four flashes means something wrong in the power supply, but I haven't been able to get any further. Hopefully this isn't an MCZ chip failure.

the service info was very easy to find, and free.
