Question about Compaq Presario R3000 Notebook

Monitor Screen won't light

My son-in-law looked at the laptop - he's a techie - but hasn't seen this problem before and isn't sure what to replace to fix. The laptop works just fine, but the screen is totally black. If you shine a really bright light on the screen, you can see the images. We don't want to spend $$$s just to replace a $5 part. (Electronics guru husband salvaged $1000 big screen by knowing how to replace (literally) $0.50 part.) Any ideas? Thanks!

    My Compaq Oresario R3000 has a problem with a dark screen. The left half is darker then the right. THe right side seems to flicker and I expect it will go dark soon. Any part numbers or suggestions?

I had the same problem and researched it online. If you can still see the screen if you flash a light on it, then the LCD inverter inside your monitor has gone out. The problem is easy to fix and you can find a LCD inverter on ebay for $10-$15.00 for your exact laptop. Also just search the net for "replacing LCD invertor walkthrough" and you can find detailed instructions including pictures. This will solve your problem :-)

I had the same problem, or sounds like the same problem. I have the extended warranty and sent it to the shop.

The problem was that the 'Inverter' had failed. I believe the inverter changes DC current to AC current.

I hope this helps...Ken

Its the liquid crystal display fluroscent backlit, its probably cracked, damage, or not connected right, you have to take apart the display and remove it or connect it right.

Compaq presario cq62-413nr screen is black and won't show on external monitor


We had this problem several times, even sent it back for service when it was under service plan. It was fine on arrival for service. The "non-techie" solution we came up with... pop the battery... the key series in the book doesn't work, hard reboot doesn't work...unplug doesn't work... the only thing they did during the shipping process was removed the battery so we tried that and it seems to work every time.

( Dell xps m1530 laptop ) Monitor blank, powers up but screen won't come on.


It ISN'T the LCD screen. Since you diagnosed with an external VGA monitor, you now know the problem is the laptop.

(When you connect an external VGA monitor to a laptop, you are bypassing the Video Cable, and LCD screen. You are connected directly to the laptop )

The basic Windows files aren't being found. The boot files. This may mean a bad Harddrive.

Do you have the Restoration CD Disk? Laptop on insert it into the optical drive tray, close the tray.
When asked choose - Repair. (Non-Destructive Installation)

If a checkdisk is done, you have bad sectors on the harddrive.
There IS a special procedure in replacing a harddrive.

If left unplugged fro the laptop for a few hours, or if the charger itself is moved from room to room, occasionally we get an issue where the green light that indicates power does not show up at all. The...


If light you are talking about is on the power supply itself, you need to replace the power supply. Look on E-Bay.

If the light you are talking about is the AC power light on the laptop, then there are two things that are most likely. First is the power receptacle in the laptop. I have personally seen many of these fail. The other thing is the battery. With the system Off, and power supply disconnected, remove the battery. Wait a couple of minutes and put back in and plug in charger. If it continues to happen then it is most likely the power receptacle in the laptop.

Best of luck, Jim

Screen will not start - blue light on LG start up flashes on and off about every second? Not the pc backup screen is fine - is it fixable?


check the monitor on a differant pc or laptop to make sure the problem is the monitor. Unfortunetly unless the monitor is under warrenty it isn;t that cost effective to fix. The price to repair will be as much as a new monitor.
The parts are cheap but the labor isnt. So if you can find some to look at it get an extimate and know what a new one is worth before spending any money.

I have got vga leads for my lapto to tv , they work with my 14" laptop but won`t work with my sons 7" laptop


Things to try:

1. make sure that the vga port is enabled on the laptop usually its
function key and an F key that has a (O) looking symbol above it you may need to toggle it more than once.

2. try a different screen resolution.

3. test the vga port with a standard old monitor to make sure that it works.

When powered up, the desktop is barely visible.


You probably need a new inverter or a back light replacement for the screen. Any good techie can do that for you, and not all that expensive.

be sure to circle through possible screen.
use FN key + a key with a screen symbol on your keyboard (or check your doc) to switch from main screen to external monitor and back.
sometime some techies use external monitor for pc final test and forgot to restore configuration to laptop screen.
At restart XP is expecting the last used monitor and nothing shows on laptop screen.
try also connecting any external monitor to vga plug.
let me know if is fixing
