Monitor doesnt switch off

[dembee]

When I 'Turn off computer' the monitor will no longer switch off. When the processor shuts down the monitor alternates between different colour blank screens and will not switch off. Has anyone any idea what the problem could be and what can be done? Thanks.

Push the on/off button on the monitor perhaps.

That is the problem! It won't switch off unless unplugged.

Sorry not being a smartypants I misunderstood. Some Computer set ups, power down the computer and then put the monitor into standby or switch them off.
If you are on XP. You right mouse click the desktop-display properties-screensaver- then at the bottom you have power settings.
There you can select if you want the monitor off etc.
It has got to be a faulty switch really as this over rides everything (apart from unplugging it as you say )

I had exactly the problem that you describe with my 7 yr old computer - not much memory and Win98.
I spoke to several so-called experts who diagnosed a faulty monitor and / or a faulty graphics card. Both of these explanations seemed feasible as I had been - and still am - having problems with the monitor brightness randomly changing from normal to darker and back. This suggested a faulty switch or connection somewhere along the line but I couldn't find anything amiss.
In the end, I started browsing through catalogues with a view to actually lashing out on a brand new shiny replacement computer. I shut everything down via the mains switch and went to the pub.
This is my usual solution for all my problems and it worked!
When I switched on next morning everything was back to normal apart from the computer auto-running scan drive which it does when the system hasn't been shut down properly.
I still have the variable brightness problem so there is something slightly amiss but apart from that - no problems.
I am putting the problem down to one of life's little mysteries.
Incidentally, have you tried holding the Power switch in for 5 or 6 seconds when you can't switch off?
Sorry for the rambling - hope it helps - or at least gives you some comfort.
