Great reply from our Computer Guru Larry. Let's put it down here, because it is now solved :>)
- all monitors made for 2 decades to that , and buy law in USA> called Energy Star compliance.
NO PC told nor OS told w can not guess PC nor what OS you run. not ever.
make and model PC not told nor if using VGA/DVI/HDMI or DP connections.
wow 14 years and finally fails. (amazing luck there and 99% of 2007 monitors are now dead, 8hr/day ,365.
the answer box 1 , is you can not do that. in the monitor. by law. hard coded. here see why./?
see sleep loop inside MON firmware, yes there it is .https://pcdied.com/BIOS/e173flow1.jpg
All monitors go to sleep for 2 reasons, PC went dead (by law)
or PC actual is in sleep mode.
all PC sold are coded (settings) to do that by law, OOBE (out of the box experience) by law.
so if using windows are you?
yes, then click CP control panel, the power setting an turn off sleep to the MON
or learn to google?? or ask any kid ,they know for sure.
windows 10 (but gee 2007 is XP or VistA)
google how to turn off sleep in windows.
that power menu , control every thing in the PC that can sleep.
USB ports, Nic cards, Monitor GPU ports , HDD and more, and all your choice on 2nd day owned.
on desk top we just end sleep by hitting space bar (easy close wide key) or wiggle the mouse.
or if set right in same place, the power button ends sleep pushed fast.
on some old PCs, letting USB sleep, makes mouse and keyboard dead. (painful)
mouse usb, fails. to unsleep
in device manager,, go to mouse
then right click properties on it.
tab power management , allow this device to wake the computes.
and do not allow hibernate mode, in power settings, it things can get ugly fast
now the ELEMENT in the room.
the PC came with XP I bet, 90% did and if upgraded and the PC maker does not allow,
w7 or w8 or w10 at all
then the drivers are bad. and bad drivers LOVE TO FAIL FOR Sleep.
NO PC told
no OS told
hp 27,is what?
see why here
the rear of a MON shows a tag with true model
a desktop has 6 sides, one side has the tag, even bottom side.
not told that.
the monitor tag will show model and p/n or sku.# and nnnnnnnn#ABA
the ABA is the true product number that also shows and tells options in it DAY1 new.
like how many ports there are and what kinds of ports. and more.
example (sorry googe will not let me see one year of 2007 monitors or Id guess better (grin)
HP 27" 3UA74AA#ABA (LED,) so is newer, your is CCFL lamps, 2007 most are.

all I have are questions, and list of tests. One VRM saw a short and shut down as it must, to not burn up.VRM job (partly) is to act as a FUSE. (pure electronics fuse)you must find what is shorted, for sure it is a module of any kind inside, if all USB port are unplugged,even USB cables can short, some system shut down like that, others just the VBUS chip to it shuts downnot sure if you have POE ethernet ports there?> nah not there, power over ethernet. so can not short outside.that new MOBO was it preloaded with RAM and CPU or DEPOPULATED ALL THINGS.
