CRT does not work, likely you have dead capacitors in the power supply, the monitor board also has some dead capacitors, a few high value resistors in the CRY bias have drifted high, and the 2A fuse on the board is blown because of dry joints on the LOPT base and the scan coil plug. Other than that a dead line transistor because of the dry joints, or dry joints on the line driver transformer or the base pull down resistor across the driver secondary. Beware of low value high voltage electrolytic caps there, they can go open circuit or very high ESR, and give odd symptoms.
Not too hard to fix those, done a few in the past, and the board layouit will be similar amongst all the assorted chassis variants they used. Still have one at work as a spare CRT display for a camera, Panasonic and still works well, though the tube is getting a little tired.
