Question about HP Pavilion F1903 19" Flat Panel LCD Monitor

2 Answers

My F1903 will come on for a second or two when I turn on my computer, but then the screen goes black. When I can see the screen, everyhing looks fine. Does anyone have any ideas? Also, it started going off like this after hours of use. When I would restart the computer it was fine. Now it does it immediately.

Hello.

I very much disagree with buddymc's solution to this problem. I am looking at an hp pavilion f1903 right now with EXACTLY the same problem that you described. The screen will come on for a second or two, and immediately shut off.

If you look closely, however, I suspect you might notice something more to the problem. The screen is actually still on! If you hold a flashlight up to the screen after it "turns off," you might notice that it has text/pictures still on the screen, although they are very hard to see. If this is the case, then your only problem is a broken backlight. Although fixing a broken backlight is no easy task, there is an online tutorial here (http://inventgeek.com/Projects/BacklightFix/Page1.aspx) if you want to check it out.

I highly doubt your problem is a bad power supply in the monitor. If that was the problem I doubt the monitor would come on at all, even for a second.

Hello,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

When i turn on the monitor it flashes on once for a few seconds t


faith1114, Try this first! See if any thing seems a little similar to your f1903 type of complaint. Problem been around a long time!!! Go do some reading here: http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution. After doing some reading there, you will be in a better position to make decision to DIY repair, contract out the repair work, trade in for new , DIY repair + buy a new monitor keeping refurbished f1903 as emergency spare. Here is a little clue. If unit can display Win-desktop for 2 seconds and then the "black screen of death happens" you certainly need to do some reading and viewing of DIY videos at YOUTUBE so you can understand the big problem all major CCFL back-lit lcd monitor manufacturers are facing. do some additional reading here at fixya in the profiles of ccfl backlit lcd monitor technicians "budmrtn" "buddymc" , "12fixlouie" (late) "louie12fix" (old) Follow links you find there. Once you understand basic problem you will never walk past the new curlie-Q, screw-in energy-efficient CFL light bulbs at the local hardware or big box homecenter ever again with out having a slight grin on your face!! Bye for now. 12fixlouie

Hp f1903 flat pc monitor goes black after 5


I was given a faulty f1703 by someone as it was out of warranty, had no help from HP and bought another brand replacement.

Same problem everyone else seems to be having. Press the on button, came on for a second or so and then went blank. Press button again, turn on again and the same happened.

I managed through trying time and again after pressing on to quickly press menu, then go down to Factory settings, press select, go down to Yes and press select again. This reset to the Factory settings and it seems to be working okay. Been like this now for about a week. I don't know how long it will last - if it goes again will try re-soldering. Guess I won't be buying HP products as this was a part of a very expensive system.

When turning on my monitor - the blue light is on


This could mean that you video card is bad or going bad. Also that the monitor is going out too. Its one or the other.Try to plug the monitor into another computer to test it first. It will give you an idea where to start. then move to the video card.

Hi

You have parts on the power supply board which are going bad. You can send it to a company like mine or take it to a local repair person.

Pavilion f1903 silver goes blank seconds after turning on.


The monitor you have has bad components on the circuit boards inside.
This is a classic problem with all LCD monitors.
I rebuild them on a daily basis so I recognize the symptoms.
I would suggest finding someone who can do component level repair on the circuit boards inside.
I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.

Monitor going black


HP's are known for bad capacitors in the power supply.
Replacing them is simple if you know how..not so simple if you don't.
Try your local TV repair centre. It should not cost alot to have the capacitors replaced.

Hope it helps =)
