What causes a dark screen and a flashing power button for a HP Pavilion F1903 19" flat screen monitor?

Also look for bad caps in the main power supply and the fuses on the inverter board.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.

Problaly you had a magnet near by that caused that Dark Shadow.

it sounds like a capacitor blew from the inverter board.. if u can open it it should be obvious which one the messed up..

Have you tried connecting this monitor to another computer, even a laptop. This would tell you whether the display is bad or the video card is the culprit. I suspect the monitor's power supply is dying. Taking it to a pro for repair should cost @55.00. Buying a new monitor @ $100 - $125.

COULD IT BE THE INVERTOR BOARD?

Try reinstalling your monitor. You should have a disc that came with all of your equipment.Make sure it is a clean install and there are no other programs running. Also check all connections to make sure they are tight.

If this does not help, do you have another monitor you can install temporarily so that you can work on this problem?

Is this a new monitor installation? You might want to check your hardware compatibility list which you will find under Start>Programs>accessories>compatibility wizard.

THis is a problem of the invertor board.If you are technically able you need to disasseble the monitor and resolder components around the red or yellow inverter transformers.

Ok I got the same problem. And this is the way how to examine where the problem is. You have to check that you can see the image on screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Found cold solder joints, re-soldered and monitor is operating properly now.

welcome to first time English dot com ! really !
this is texting, it's what ever you want.
so you have a dead monitor? does the OSD work.
that is first, OSD if the ON SCREEN display fails the monitor power pack is dead or the monitor is dead,
monitor schematics can be hard to find
but 1second google search and i see this.
learn to use google?

no symptoms posted, or full English , here ill use google translate for you (so can you, dig?)
OMG the Spanish actually has facts.

"THANKS FOR ME AND FORGIVEN FOR MY ENGLISH !!
P.S. It takes a second to turn black and it seems that something causes excess consumption (low voltage 3 V.), then it is dark and the minute goes to amber, the led."

What does OSD do.
did you know a monitor is only $50 at walmart.
id bet it costs way more to fix any monitor than that.
parts, labor, shipping and bam broke.

the monitor is covered here 100% but no schematics. sorry.

read the words, my monitor is blank there? it tells you step by step what to do. well advised to read that or translate it.

the monitor has 4 buttons on the right
1,2,3,4
button 1 is OSD menu, this must work all the time with power on.
even with no PC connected. it works.
if not the power supplies inside the monitor are dead. or the power pack is dead, if it has external pack we test that next.

this monitor has LCD back lamp CCFL with inverter.
CCFL or well known to die fast or go dim or ugly yellow.
Id put this think in the trash and get a LCD with LED black lamps
in a heart beat. and never look back to CCFL junk again. IMO

id did not read your manual for you, just skimmed it,
but if it has a power pack id check that first.
then with CCFL (they sold the monitor over 17 years ago)
IF the screen goes back, we use a FLASH light, on the screen
and if you now see DATA of any KIND< the CCFL is bad.
in non geek that is "BAD BACK LAMPS" and supplies to it.


as seen here, ( if this works the back lamps are toasted)
