I have a Mitsubishi diamond plus 92 monitor and recently it has begun to switch itself to powere save go blank with the powere light going orange while the computer is booting up. It has once done this while i was working too. Rebooting normally gets it going again though sometimes from a cold start up this will need to be done 3 times before the screen stays on
any ideas

Re:
The graphics card or onboard graphics driver may not be kicking in at boot up causing the monitor to shut down, check the graphics card connector for bent pins and both connector ends.
If you are able, think back to when this started and use system restore to a date before is started.
Also you may have inadvertantly updated your graphics driver with one of windows generic drivers, of which may be the cause.
You can also try pressing F8 on boot up and selecting 'last known good configuration' and see if that cures it.

Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU. It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.
Replace the power switch. If you can't find a replacement part open the case and solder the connections of the switch so they will be permanently on. You can place a new switch on the power cable.
My Friend you have a problem in the power supply, you try voltage check, check if you have output in the b+. if nothing, there is a regulator in power section, for example ic401, you look at the board you will see all the components section of ic401, all the capacitor have 4 for example c423 or resistor r423 like that one. You check all the section of the power supply. Hope I help you. bye
Complete service manual with an error search tree , sometimes there is a vertical ic defect by deformed capacitors hanging around that or a powerline from powersupply failed (sometimes there could be a defect fuse resistor to find ) or only a bad factory cold soldering by manipulate some passive components somewhere in vertical stage .
You have tried the monitor on more than one known good computer, yes?
I believe about 4" inside this monitor in the back the vga cable or connector connects to a board with an in-line connector. Can you see if this connector (internal to the monitor) in connected?
