Question about HP Pavilion F1903 19" Flat Panel LCD Monitor
Most of the time the power capacitors on the power supply have gone bad. There are three of them in the power supply, 1000uf 12v on the left side of the dual transistor heat sink looking at it with the heat sink toward you. Go to Radio Sh and get three new ones(1000uf 12v min, as long as they fit 1500-2000uf 12-16v? does not matter) and solder them in. The hardest part is taking the front basil off the monitor. there are no screws, insert something strong and thin where the two half's come together and carefully start it apart. The LCD unit comes right out along with the power switch board. Remove the two screws at the bottom of the power board. The for back-light plug in's and the two screws from the main AC plug. The other plug in is a multi wire that unplugs from the other board. Replace the capacitors and reassemble. This goes wrong with this model all the time and is not as hard to do as you may think. What do you have to loose? Most likely save $150 bucks.

There are 3 bad capacitors on the pwr supply bd (C822, C823, C824) I changed them for a buck each and the monitor worked.
Here are links to a pic showing the 3 capacitior lower right just above the data cable and the fix.

I posted to this list about a month ago. Monitor would not power up. Here is an update. I was able to fix the problem. There were two capacitors on the power board near a heat sink that looked bad. The two capacitors were radial type. The bottom of the capacitor should be flat. These two had a slight dome to the bottom. So I took a chance and replcaed them. I am now sitting here typing this memo looking at a fully functional monitor. Not sure if it will help but this is my finding.

Go here for the solution to a similar problem. If busted caps are causing it, this is the solution. Cheap and easy:

To remove the program creator 9 of my comp. shuts down and turned the comp. and the monitor turns off completely. I sign the comp. on the tv. I can do with my monitor

Well, isn't this a coincidence? Exact same story... within a month of my warranty finishing, my monitor dies. The problem is that the power supply is dead. Yes, a new monitor is 250-300 dollars, however to get the power supply fixed at a place like staples, its going to the tune of about 220$... which is not much better. Not impressed. I'm going to call HP again tomorrow... they are not very nice on the phones there. They told me they'd send me a replacement twice and it never came. Not impressed.
