Sony GDM-FW900 CRT Monitor Repair

[midmit]

Hello, my FW900 is currently dead. No lights, noises, nothing at all.

I've checked the fuse etc.This leads me to believe the power supply G board is the problem.
I have the schematics and a basic DMM. I'm currently trying to work out what exactly I can check.
With the board removed, the brief measurements I did take all seemed to be either -160v or 170v! A little high I thought. The fusable resistor at R610 is ok.

The board does feature a mcz3001 IC which appear to be common culprits on Sony TV sets.

Any help at all is greatly appreciated. I'm determined to get this going again.
