Try to see if this works on another computer first, if it does, then it assumes the monitor is ok.
Then as the computer boots up, boot to safe mode by pressing F8 and once in that state, set the display to a mode that the graphics card will support.

- Larry Ng Jul 15, 2021that is just a YEAR 2007 LCD computer monitor, it needs a computer to work. if it fails in a 2nd PC ,
if that test fails,the monitor is bad. (hardward failure, monitor.
the tests are simple,
it fails on 2nd good PC, what can be more simple that test ANY 14 year old monitor on a 2nd good PC.
when dead do this.(test2)
they are all here when dead again use a FLASH LIGHT. (or in UK a low carbon foot print TORCH)<< joking.

all monitors older than 2010 do this . (has CCFL inside and that is never fun now)
the cure is newer monitors 2011 to now called LED monitor.s or OLED.
the tubes are cold cathode florescent tubes. (back lamps.) (have 5 classic fail symptoms not just dead)
they are short lived,
laptops and monitors both back then. 20,00hours on the clock and go bad. bank on it.
the 3 failures are CCFL, PSU board, and logic board
#1 is CCFL the all died long ago, on average about year 2003 (07 +5= 12, 2012) at 20,000 yours boom dead.
or intermittent.
PSU is here:
https://pcdied.com/monitors_and_screens/...
below is logic board.
one of the 3 fail, CCFL tubes dead is like 99%
we retire them if the CCFL test fails. (using bench PSU to test them) but you have non of that so. upgrade

99% of all monitors are all dead. due to those silly low live CCFL back lamps.
or the 2cards inside that can fail too. PSU card +HV CCLF power or the Data card is dead.
99.9% of folks seen these facts, upgrade now.
high voltage inside 600v on the CCFL pins
