20 Most Recent HP Pavilion F1903 19" Flat Panel LCD Monitor - Page 6 Questions & Answers

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

deepbass6, It's almost dead. You didn't say if the lcd was working fine (perfect picture) the day before. Need to know that! How old is it? "IN WARRANTY???" Although you didn't say, I suspect that you are wondering what to do, I will tell you your limited options. 1. Find out if HP has a Refurbished monitor swapout program. You send them yours+$50-$90, and they send you a Refurbished same model in return. 2. Locate local TV/Monitor repair shop that knows all about repair of the following Items: Switch-Mode-Power-Supplys and Cold-Cathode-Fluorescent-Tubes and their power source called an INVERTER circuit/board. Another name for that last item is known as an Electronic Ballast circuit. The new screw-in curlie-Q light bulbs are of the same basic technology. Only your tubes are thinner and straight and placed in front of a mirrored sufrace and hung horizontally on the rear of your lcd. 3. Check out (search web) all you can find out about BAD capacitors in lcd monitors and bad solder joints on inverter boards/SMPS boards. Try badcaps .net, and lcdrepair. us, and lcdpart.com /components, and just for a look-see-only, visit a site called electronicrepairguide.com, run by a Jestine Yong in the far east. pay no attention to his ad to sell you a course in lcd repair. ONLY view the photos of the insides of monitors and boards. youtube also has some videos of monitor disassembly and repair kinds of stuff. Well it's still a little cold for me to visit the gravel pits in s.e. side of Crystal Lake Illinois Virginia Rd and Pingree Rd on my lunch break. Hope this info was of some use. I'm louie12fix on fixya or email lmistyrel @ aol.com.
BYE for now.

try to see maybe it is mute or inspect the connection of your speaker to your audio jack.i think there is loose contact of your speaker.

If the screen is flickering then I would assume its a dry solder on the inverter board or the LCD panel is about to die. Are you skilled in electronics?

Fixed the register problem with RegCure software.

This is how I learned to open my f1703hp monitor not sure if f1903 hp is the same...I got my open and going to replace power board waiting for the mail LOL.

The problem is with the inverter board. It is pulling down the main power supply and cycling it on and off (crowbaring). If you disconnect the power supply cable to the board, the power supply will stay up and the power on lamp will cycle as normal. There seems to be a problem with one of the high voltage transformers on the board. I will let you know if I can find a suitable replacement of if there is a way to get an inverter board inexpensively. Good luck!

Use commercial glass cleaners that do not contain ammonia, or use Isopropyl Alcohol, or do it simply, use Water with a tiny amount of soft liquid soap.

Good luck to you!

If you find my answer helpfull, dont forget to vote!

What you are seeing is a test they use at the factory. Here are the instructions to reset the monitor:

1. Press the MENU button
2. Use the + and - buttons to choose Advanced Menu
3. Press the SELECT button
4. Select Factory Reset
5. Select Yes
6. Press MENU again to remove the onscreen menu

Hope that helps :)

There is a common problem with the power board that needs about $6 USD in parts from radioshack. Search Instructables at the MAKE site...

There are three (3) capacitors that go bad on the power supply board. MAKE magazine's Instructable site has a good guide on replacing them. I have a june 07 and july 07 date monitors. they were different inside!! identical outside, however. The bulged,'bad' components were 1000uf 10v cap's, I put in radio shack 272-1032 1000uf 35wvdc. My monitors? BOTH were bought for $35 on craigslist, $10.35 in parts. ???BusinFLA -at- hotma*l dot com.....worked for me!

internal power supply failure in the monitor generally repair is more costly then replacement,that can be verified if you can find a tv repair shop that provides free estimates.

may you just uninstall the first video card driver & monitor driver, & then install it again..

please post back & let us know here, how things done..

Thank you

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 =)

You need to match the capacitors to the parts removed from the PCB.

Hi,
Sure you can. As long as you what the value of the capacitor.
Or you bring it to the radio shack showing the sample.
If don't know how to open it . You can visit this site:

www.lcdrepair.us

There video clip inside where will teach you how to open it.

Goto your local Radio Shack or computer shop and ask if they know of any repairers in the local area. Chances are they have someone from such a place they supply equipment or parts to.
If you were in Australia I could do it in a flash.

Hope it helps =)
