It could be your inverter board that has died. It's a small board behind the bezel just underneath the screen. the inverter board powers the backlight.

You can also connect to an external monitor from a desktop. holding th FN button and usually f5 will toggle between the displays. 
The second method if the monitor turns blackl this machine is out of warranty is remove the bezel surrounding the lcd. remove teh screws that hold the lcd in place. Shine a flashlight behind the LCD with the machine on. If the Backlught is bad you will see windows or dos dimly. At this point order a replacement backlight from Ebay or HP.. PJ

Either:

your backlight on the monitor is going out.

or

The powersave functions are out of whack.

Check your settings, reinstall the display drivers, if that doesn't solve it, it's a hardware issue.

To verify boot from a DOS boot disk or linux (something text based), and see if it's still dark. It's probably a hardware issue.

The lcd display has become very dim on my sony dreammachine icf-c218 how do i brighten it up?


There is no adjustment on this model. Mine was too dim and the only way I was able to make the display brighter was by removing the front lens. I then used a nail and a knife to scratch and cut (from inside) the rectangular area of the lens in front of the display. It looked nice afterwards. If you need it dimmer, I would recommend putting a small shaded sheet behind the lens like the ones used for tinting car windows instead.

Lcd lights got dimmer


First check to make sure the power adapter is connected to the laptop properly, if not it runs off the battery and the display is dimmer.
Second check the brightness setting, you can adjust the brightness by pressing the Fn key plus the F7 or F8 keys to adjust the brightness.

If this doesn't work then :-
The problem/fault could be one of several things. Could be the CCFL lamp, the inverter that supplies high voltage to the CCFL lamp or the video card.
The video card cannot be replaced on a laptop, it is part of the motherboard.
To determine if the video card is faulty, connect an external monitor to the external video port on the laptop, power up the monitor first and then the laptop. The video output will switch automatically to the external monitor, if you see a normal Windows image then the video card is OK.
Next, shut down the laptop, disconnect the monitor and power up the laptop. After the laptop boots up look at the LCD screen at a sharp angle and if you see a dim or dark image then the fault is a faulty CCFL lamp or inverter. Most likely the CCFL lamp is faulty, but the inverter is easier to replace.

Multiple lines on screen


Try connecting an external monitor to the your laptop and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

The lights on the instrument panels as well as the radio flash at intermittent intervals. There seems to be no rhyme or reason as to when this happens (i.e. hot or cold car, bumps or no bumps, turns or no...


I had intermittent instrument light problem that went dark for months, until today. :o) I read somewhere that it could be the dimmer switch and didn't think that was my problem as the dimmer worked (dimmed the radio and transmission indicator light) and playing with it never seemed to help with the problem. I did find it odd that dimmer was not completely linear, as it would get brighter up to a certain point and get slightly dimmer with the last little bit of travel.

Today, I took the instrument cluster apart to fix a broken clock, sticking gas & voltage gauges, and to explore the instrument light problem. I took apart the dimmer switch, and to my surprise (was expecting a simple POT), it was a very complicated PCB with some IC's, resistors, transistors, etc. I thought, "all this just to dim the light???" Anyway, I found the POT (potentiometer) and gave a few squirts of WD-40 and found it turning smoother. After putting it back together, the instrument light came back and the dimmer is now perfectly linear. Apparently, less than perfect POT causes some sort of funny logic through the network of IC's and transistors and can cause the instrument light to go on or off randomly at certain intervals.

Anyway, I'm so happy to have the light back along with a working clock and not having to punch the instrument cluster to see how much fuel I have. Not really a posting type, but wanted to help someone else out there with a similar problem with same cause.

Compaq Armada M700, Dim Screen


There is a dimmer function that is part of the keyboard on most notebooks. You use the Fn key and some other key (Mine is F1 and F1) Look for what looks like Sun in blue print on the key. You should find 2 of them. One will be the brightness up and the other brightness down. You can try those.

More likely, something has come loose internally.
1. It could be the backlight for the screen is broken or a connection loose. You should be able to see the light when you look at the side of the display.
2. The AC power connector may have been broken and the notebook is only on battery power. By default most systems are dimmer when on battery power. Check to see if your charge indicator light is on. If not, that may be the problem.

I hope this helps.
