I switch on my PC, ensuring that all cables, leads
and power supplies are connected properly. The tower powers up no
problems at all. I switch the screen on, the green led lights up, the
screen is completely black. A blue box appears centrally on the screen
with the text 'power saving mode'. The green led light turns amber and
then the screen just goes black.
Please don't suggest going to control panel, as I can't get that far.

Your site is extremely misleading and fraudulent. I was under the impression that I would at least get a hint at what might be a problem instead of you folks making me wait to get a money for something answer that you could have displayed on your main page.

Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4
bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
