My wife's compaq presario f700 turns on yet the screen is really dim to the point of almost being all black! I can see some things with some strain or added light. Please advise.


Screen backlight is probably failing, the fact that you are getting an image suggests that the inverter is ok (although replacement is often the only way of telling).

Firstly, plug the laptop into an external monitor, if the picture is clear, this will confirm that the issue lies with the backlight or the inverter, if however it does not, then you may have issues with the onboard graphics chip beginning to fail (expensive as it will need a new motherboard).

The only other cause can be a damaged VGA lead (unlikely).

Best guess would be that the laptop screen needs replacing, as replacing the tube for the backlight is a very difficult task and not really worth the effort or expense. You can find some good 2nd hand screens now for a 15.4 laptop quite cheaply and replacement is very easy

Compaq presario 700 monitor off


Hi
Maybe, depending on the problem. Laptop monitor problems fall into three categories. 1. Screen electronics or lamp. 2. Inverter. 3. Laptop video chip. I've been repairing latops ever since they arrived on the market. First connect an external monitor to the laptop - this will show you whether or not the laptop motherboard is working correctly. If it is then you'll need to replace either the screen or the inverter. So as not to waste alot of money, at this point I would suugest going to a reputable repair person or check my website www.micromendllc.com

Periodically the screen is captured by horizontal lines completely across the screen. Cannot access programs or even shut down properly. Any suggestions. Presario 700 laptop using Windows Vista. Thanks


This issue is due to the malfunctioning of the screen or due to any other internal hardware malfunctioning of the notebook.

To further isolate the issue, I request you to connect the external monitor and check.

Once after connecting the external monitor, please tsp Fn+F3 Switch between the display and external monitor in the following order:

Display
External monitor
Display and external monitor

If the external display is fine then the issue either could be due the malfunctioning of the display cable connector between the screen of the notebook and motherboard or due to the malfunctioning of the screen.

As this the hardware issue, Please contact the nearest repair center to get it resolved.

Presario 700 has a blank screen. Started occasionally going to a blank screen, now it stay blank. Will replacing the hard drive correct this problem?


If the laptop appears to boot up and the hard disk is spinning and the hard disk LED is flashing then the hard disk is OK.
Then the fault could be a faulty video cable or connector or CCFL lamp or inverter.
Try reseating the video cable/connector that connects to the motherboard first.
If this doesn't work then to determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.
