If the backlight is an intermittent problem, it is likely that the video connector and or the backlight connector needs reseating. There are usually two connectors that connect the LCD display to the motherboard. You need to pull apart your laptop to reveal these connectors (these connectors are usually near the top edge of the laptop). Unplug and reconnect these connectors to re-establish a good connection.
Take note of the locations of the various screws when you remove them (some vary in length) so you can put them back in their correct location.

Laptop backlight won't come on


Hi Fletcher,
Nowadays laptops come with an option to turn off the backlight to save power.
Since you have not included the model no of your laptop, i can't give specific info on how to turn on the backlight.
You can check the user guide of the laptop.
If that is not the case, the backlight board might have gone out and needs to replace it.
If you don't know how to do that, i would suggest you to contact a technician.

My hp compaq Presario V6500 has been damaged and a computer dude in Bathurst NSW said we need a bulb replaced in the screen as it won't light up. Computer functions via TV. R there any local repairers for...


The monitor screen on your laptop is an LCD screen.

An LCD screen cannot produce enough light by itself. It needs an additional light source.
The additional light source is a Backlight.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

LCD screens are a composite of layers. The layers are held together by a metal frame, much like a picture frame.
The Backlight is usually located on one side, accessed after removing one side of the metal frame.

As stated, a Backlight is a very small type of Fluorescent lamp, (Tube)
Very fragile, easily breakable, and not usually approached by one who has very little, or no experience in replacing.
More common the entire LCD screen is replaced, which includes the Backlight already installed.

A laptop also needs an Inverter to provide power, both for the LCD screen, and the Backlight.

90 percent of the time the fault is the Inverter.
I repeat, 90 percent of the time the fault is a bad Inverter.

An Inverter is cheaper than an LCD screen, and MUCH easier to replace than a Backlight.

Allow me to show you replacing an Inverter on an HP Pavilion dv6000 series laptop.
Granted, it isn't an HP Compaq Presario V6500 series, but the principles still apply the same,

I can also provide a free link, to the Service Manual for an HP Compaq Presario V6500 laptop, direct from HP Support,

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=3369429&

In the list click on;
Compaq Presario V6500, V6600, and V6700 Notebook PCs-Maintenance and Service Guide

This is a PDF file.
Allow up to 30 seconds to see the first page, and an additional time may be needed to fully download.

In the Bookmarks menu on the left click on the + sign next to;
1) Removal and replacement procedures
2) Component and replacement procedures
3) Display assembly

And/or go directly to Page 61 to view the Inverter location.

One example of an Inverter for an HP Compaq Presario V6500,

Granted this is not what you asked for.
My premise is to teach, and hopefully save people money.

Dark screen on the half lower portion of my laptop


Hi,

The CCFL backlight bulb is on its way out. You can either purchase a new buld for the laptop screen or replace the whole screen itself.

If you just want to replace the bulb itself then click on the link provided below.

How to replace backlight on compaq 2570us laptop


What is wrong with the backlight? The computer screen is just dark? I would start with the inverter. The inverter is usually the problem when the screen goes dark but people think it is the backlight. The backlight alone is very hard to change too. Go with the inverter, I would bet that is the issue.

I want to have a wifi driver in my laptop so that i can connect to the internet through wifi.


Here is the page containing the info for your laptop and the drivers:

Keep in mind that if you have windows xp on your laptop it won't have the drivers for the wireless card. If you have vista on your laptop then choose vista and then the driver for the wireless card will be in there. Just download it and install it. The laptop should recognize the card at that point.

Backlight Life


Yes by leaving the laptop on all the time you could burn out the laptops back light. Set your power settings to turn monitor off after so many minutes of non use to save this. Further more I would recommend a chill pad under the laptop to help keep the CPU from getting to hot.

How to install back light in compaq presario r3360us


Hi there.
The backlight or inverter is located at the bottom of the screen behind the bezel (plastic screen surround) it's an elongated circuit board hidden behind frosted plastic, you can't miss it as all the connectors from the motherboard and the screen are attached to it.
If you need any more advice please feel free to post back.

Good luck and thanks for choosing FixYa!!

Compaq laptop with dark screen


It is possible that the problem is in the video card - that it's just not turning on the backlight. But it's so much more common for it to be the backlight or inverter that I'd try to get a second opinion.
