Sony GDM-FW900 CRT Monitor Repair

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.
 
If you send the schematics diagram I will help you.
