When I power up the unit, the power switch illuminates (green) but nothing else. I've checked the (two) pcb's for obvious signs of damage but theye are pristine in appearance, all tracks in tact and no obvious signs of heat damage..
Does anyone have a service manual for this item, or perhaps details of voltage checks I can perform?

The first thing to check is , the Power, are ya sure it's plugged in OK, are ya sure that socket is working, try something else in that outlet to prove, check the power cord is pushed right in, Check ya on the right Video connector on the PC, make sure all conns are correct. Try the monitor on another base unit, try your base unit on another monitor. If all these are OK then ya Monitor has turned it's toes up sorry.
In my years of working on LCD's, your inverter (basically like a ballast in a flourscent lamp) is bad/going out. Crack open the case and look for a big pink and white wire going to a pcb (usually located under a shield) and remove it and check for puffed capacitors. If there are some change them and that usually fixes the problem. If there are no signs of anything wrong on the inverter, get the numbers off the pcb and google or ebay the numbers, usually youll find a replacement realitively fast.

This problem is now resolved and the monitor fixed and working.
For reference - it was nothing to do with the ON/OFF switch at all.
The Power Supply / Inverter PCB had two duff capacitors.
These were replaced and BINGO - a working unit.
For other reference - had absolutely NO assistance from any of the users of the various Forums I tried - NO suggestions - NO nothing.
I remember my Grandfather once saying "You get nothing for nothing in this world lad"
Not even advice - He was right.
