My monitor worked great for a year, however, recently after long periods of inactivity (over night) the monitor will not detect the signal from the computer. I have to shut the computer off and restart it, then the monitor detects the signal again. Is this happening to anyone else ?

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.
If the monitor is black either the computer is not sending signal to the monitor or the monitor is getting the signal and its broken.
1.) does the old monitor or another monitor work with the computer you have. if yes your monitor is prolly broke since there is not much to a monitor they automatically detect signal as soon as its turned on.
2.) if the monitor doesnt work the old one then your computer is the issue and it can be a lot of things can cause no video
I suspect the invertor supplying power to the Xenon backlight tubes has failed.
This can be reapired but may not be cost effective.
Ask for a quote from your local computer specialist but keep in mind the cost of a new monitor.
You'll need to check the cable connections and the computer that it is attached to. The monitor may be going into standby mode because the computer went into Suspended/Hibernate mode. Try restarting the computer. If you're unable to do this, try a hard power off and then try to turn it back on.
I'm not too sure about dell pc's.But if you think a fuse might be inside there,I'd try to do a search online for how to change that and go from there.However,I'm not really understanding the warm up thing.Is it an LCD screen?
