I had a P810-1M monitor. Im not sure if it is different from yours.
Check the FCC number. Mine is GSS21001 August 1996
It has the same chassis number.
I do have a service manual and schematic for mine.
Check the FET transistor that drives the flyback transformer.
E-Mail me if you need more info.

Thanks for the reply John,
My FCC ID is GSS21001 August 1997, so same number but a year younger if that makes a difference.
I've done some testing against a manual that I found on the 'net and it seems that I am getting only 14vDC at Q820 (2SC4620) where I should be getting 125vDC!
This transistor seems to drive IC820 (STR-S6531) which I can't seem to find any information on.
However, when I connect my multimeter between any side of R806 (336vDC) and earth (on volts DC scale), the clicking stops and the degauss circuit seems to operate as normal!
I have the thing in a million pieces right now so I don't know if the screen is actually working when the clicking stops so I can't say for sure, but it seems to temporarily cure the problem.
I'm going to investigate this a little closer but any further help would be greatly appreciated.
Regards,
Kevin
