How low has the brightness gone? If it is very dark and you can barely see anything on the screen, it may be that the inverter board has failed and needs replacing.

The problem could also be caused by the screen itself, or the motherboard, but the inverter is the most common solution.

Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim rather than a slow degradation, the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

I don't have anything on the screen on my presario v5000. When i power it on, i see the word compaq but it's very very very pale. I think it could be the inverter. Can you confirm or help me. Yvan


Hi Yvan!

Even if the inverter is the problem, it should go past the Compaq logo, it should still boot to windows as normally as it should.

If it boots to Windows, it's an inverter problem, if not, then it's something else.

Best Regards,

Ben

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.

Without more information i would have to say that your inverter has died. The inverter provides light for your screen.
