In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Hp g5000 sreen does not light up as usal, i can see a the start up when i shine a torch at the sreen, what do i need to do to get working.


An LCD screen cannot produce enough light by itself. It needs an additional source of light.
A Backlight is used as the additional light source.

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

The LCD screen is a composite of layers, surrounded by a thin metal frame that resembles a picture frame.
To one side of the LCD screen layers, and under the frame is usually where the Backlight is mounted.
[Note* Two Backlights are used in some models]

Replacing a Backlight is more labor intensive than replacing an Inverter.
Due to this, and the cost, the LCD screen itself is replaced as a unit most of the time, when it comes to Backlight replacement.

Example of a replacement LCD screen for the HP G5000 series of Notebook PC's,

https://www.screentekinc.com/HP_G5000_Series--15.4-inch--1280x800-wxga-laptop-lcd-screen.shtml

[Note* Stating HP G5000 is just stating the model series. When buying replacement parts the EXACT Model Number should be used. This information is located on the bottom of the laptop, in a white Service Tag.

When replacing an LCD screen, the model number of the replacement LCD screen should be matched to the existing LCD screen's Model Number.
Inverters and LCD screens are matched together. Make sure you get the correct part]

An Inverter is used to provide power from the laptop to the LCD screen, and to the Backlight.

Note* 90 Percent of the time the problem is a bad Inverter.

Example of an Inverter for an HP G5000 series notebook PC,

http://www.zlectronic.com/product/INVERTER-FOR-HP-DAC-07B035-DAC-09B017-DV5000-G5000.html

The LCD screen, Top Cover, Display Bezel, Inverter, Backlight, and various screws, make up the Display Assembly.
The Display Bezel made of plastic surrounding the LCD screen, and in front of the LCD screen is removable.
Behind it is easy access to the Inverter.

The Inverter is approximately 4 inches long, and the width of a No.1 pencil.
Usually located at the bottom of the LCD screen, and right behind the Bezel.

This article shows replacing an Inverter and LCD screen on a Compaq Presario v2000 series Notebook PC,

This pictorial guide is not for the HP G5000 series Notebook PC, but the models are very similar when it comes to Inverter replacement.
The above link is to show you what is involved.

Cracked lcd screen. Found a lcd replacement without the inverter. What does an inverter do? do I really need it? Can't i just take the one on the previous lcd screen and apply it to the new lcd? and just...


The inverter is the source of all the "brightness" of the LCD display. So, unless you use your laptop in a totally-dark room, you need an inverter.

I would try your current inverter, to see if it works, before going out and trying to find/purchase an inverter.

Lcd blanks out


It's either the "inverter" or some loose connections.
Either way, take the computer to a qualified technician to trouble-shoot, and/or to replace the LCD screen.

Monitor screen is very dim.


Hi,
you must replace your lcd inverter, you can obtain one for around 5-15 usd, you will need to open your lcd bezel(plastics)this it a common problem in this model, its easy just be carefull with your lcd. The inverter it is located under lcd, you need to remove the frontal plastic, locate the inverter and replace it. The dark it is because your inverter no longer turn on your backlight(a lamp to give brightness to your lcd inside your lcd)
This could be a hard work if you didnt have the tools or experience.
