Power on but image on screen is very faint. What could the problem be?


HP monitors are renowned for having the inverters quit working. To repair the inverter you disconnect the power and if a laptop also remove the battery. Remove the plastic bezel (edge plastic around the screen), this can be done by lightly prying the plastic away from the screen, at the bottom of the screen just behind this plastic bezel you will see a small printed circuit board with 1 or 2 screws holding it in place with wires plugged into it, you will need an exact replacement part, the part numbers are printed on the board. Most boards are readily available for around $20 or less on Ebay. Carefully unplug the wires and screws, install the new board, attach wires, replace screw(s), snap bezel back in place making sure no wires get pinched, and you should be good to go. 30 minute fix for a novice.

HP Pavillion F1503 screen has gone dark...background is very, very faint, barely able to see/read it. What is the problem? If it is a ''backlight'', then what exact is a backlight, what does it do, is it...


Most of the time in this situation, the problem is due to the backlight going out. However, there are some instances where the inverter cable is bad.

The backlight is the part of the LCD which illuminates the screen. Think of an LCD as having multiple layers. One layer has the image itself on a semi-transparent layer and then behind that layer rests the backlight (usually a florescent bulb) which shines through all other layers to make the image glow and illuminate.

More info can be found here:

http://en.wikipedia.org/wiki/Backlight

As far as replacing the backlight, I always replace the whole LCD itself, which includes the backlight.

Otherwise, you risk ordering the backlight and finding out that it was the connection from the backlight to the LCD that was causing the problem (very possible) and then you would have to order the LCD anyway.

A quick Google search turned up a couple of sources for generic replacements:

and

Looks like they might be promising. A possible source for the original HP part might be Vance-Baldwin (www.vancebaldwin.com). I have purchased other HP parts from them.

HP Pavilion 17" screen flashes on and off


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.

HP Pavilion F1503 1503 15in Flat. screen blanks out constantly


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.

Display problem


When the screen goes dark shine a flashlight in the lower right hand corner where the Start button typically is located. If you can see faint images then you have a backlight problem. If you don't see anything then try connecting a spare monitor in its place. If that works then you have some other type of problem involving your LCD monitor. In both cases unless you have the experience and tools to safely work on fairly delicate electronics this is not a repair job for the typical consumer.
