IBM L190 LCD - the LED beside the power button corner cycles green for 1 second, off for 1 second as soon as it is plugged in. The unit won't power up, the LED just cycles green/off whenever it is plugged...


It's clear the problem is the display, but you can still try these 1. unplug and replug while the both is on 2. turn on, off couple of times 3. keep the LCD on for about one hour these are anyway temporary fixes :(

HCM Monitor has no display. When monitor started it becomes on but no display.All the function LED Becomes on.


Try disconnecting the monitor from the video connection.
Disconnect the power source and allow to set for several minutes.
Plug in the power source only and see if you recv. a no signal message on screen.
If not, you most likely have a bad display board or back light problem.
If you do recv. the message, you have a problem with your video card.

Acer AL1912 19" LCD Monitor goes black after power up


With the screen connected to the pc (which is running and putting out a signal) hold a bright light to the front of the lcd - a led flashlight works well. Do you see an image? If so then circuitry driving the inverter backlights may be at fault. I had this happen with a Dell Flat Screen, and found one of a pair of transistors which drives the backlight had developed a short.

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.

I NEED HELP PLEASE!!!!!!! PROVIEW 19" MONITER.


Does the led on front of the monitor stay blue or does it become amber ?
If it becomes amber, then you are not getting a signal.
No harm in trying this : You can try to see if it is a contact problem.
With the monitor unplugged.
Use a small paper clip to run in and out of the blue vga plug holes a few times each to make sure they are not plugged or gummed up.
If that doesn't help and you know that your video cord is good, then I am afraid to say that more than likely there is a problem with yor video card.

If it stays blue then the signal is there but the screen isn't fully lighting up, leading to a failing power-inverter board or a bad bulb.

You can desolder the B+ line to check the power back to on condition. If the power lit on.It is the int cap inside the FBT has shorted.
Happy trying.
