No plug in play... don't think their dead... do I need drives first?


no country stated or if not usa what is your line power?(volts AC)
your PSU is inside monitor not outside, so uses a simple line power cord. (just wires)
12 year old monitors, found, (dead)
page one of your user guide is clear, read it yet?
seems not.,
Auto-ranging, 90 to 265 VAC
1280 x 1024 @ 60 Hz, 75 Hz (never higher) resolution settings.
those are very old monitors.. worth like $10 used.
if the power lamp shows wrong, the monitor is dead.
right button is power to the right of it is a power led that must glow.
the old monitors had CCFL backlamps before year 2010.
those are back lamps, that fail fast. 20k hours, fast. (short)
first is the power switch
2nd is a working PC with at least sync signals on 2 pins
Horz/vertical.
then the OSD screens work of not the monitor IS DEAD.
inside this OLD monitor is sleep time, turn if off with OSD menu's its nothing but trouble.
some have an OSD lock, so hold the menu key for 10 seconds
and it unlocks. button 2 from left is MENU.
see page 4-10
the guide is here. not too good , poor diagnosis sections

specs.
https://support.hp.com/us-en/product/hp-l1940-lcd-flat-panel-monitor/427303/document/c00278650#AbT3


testing
power it on, LED power , glows.
with a PC working, say running any BIOS screen only....
or running, windows, in low resolution mode 1280 x 1024
if wise set the pc up to that first. not second.
then plug in the vga cable so the MOnitor only sees that signal above. (if you do above wrong, monitor shows OUT OF RANGE on the screen)

at mon.
PUSH the OSD button, menu, if OSD is dead the montor is dead.
OSD= on screen display., (yes the LDC has brain inside)
then take a flash light . point it at screen
see data now, if yes, in the beam is data the back lamp is dead
as are most 12 years old montors now.

see those 4 cream colored connectors bottom of this PCB
those are the high voltage CCFL lamps.
2 lamps 4 ends. the lamps are bad or the board 500 to 1000vdc
power supply is dead.

My camera shows that battery is dead even though new batteries


Back when I had my canon slr, (if i remember right) the BC lamp was actually for the battery grip - not necessarily the batteries.

SEE THIS WEBPAGE for more info on what im talking about.

No power indication


The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

I wonder if this has a backlight in it. Most/or all LCD flatpanel displays use a backlight in them, namely a small florescent tube (a tiny version of the office florescent lights). If this is burn't out, or the little power supply which runs it dead, you will have a black display. The image is actually there, you just can't see it, except perhaps faintly when external light hits it just right. The display must be disassembled to check this light. If you have tech savvy, and some equipment, voltmeter, maybe an oscilloscope, you could check it out. Where to get a replacement lamp? Google it... perhaps the manufacturer.
