The printed circuit board in the lower part of the screen is probably the LCD inverter board. If you can see the image on the screen and you?re sure its not just LCD persistence (similar to the old CRT burn in except it can be fixed) then are probably correct that it is likely the cause of your problem. The only way to tell for sure that?s the problem and not the less likely florescent tube failure is to replace it and see what happens.

To keep the backlight on continuously on my lenovo windows 8.1 laptop

Backlight timer is controlled under the power icon. If it is not on the task bar on the bottom right hand side of the screen (desktop), then search for it under pc settings.

You can hold a flashlite to see the screen, i was told it might be the light bar or inverter can you plz tell me what the problem is before i spend to much money

Ok if you can see the image when you show a flashlight to it means that the backlight is not working, it could be a simple problem as the backlight power cable loose inside or in worst case the backlight completely damaged. Best to take it to a service center and they will be able to tell you what happened. Hopefully it's just a loose cable.As LCDs do not produce light themselves they need illumination (ambient light or a special light source) to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel.Backlights are used in small displays to increase readability in low light conditions.You can search for info on Backlight to learn more about it.

Screen is to dark. cannot see letters very well.

Suggest you press the Fn key And the key to increase brightness, first. (Should be a key that has a sun icon on it)

Barring this does not increase the visibility of your LCD screen, the I suggest the Backlight is bad, or the Inverter.

The Backlight is a type of CCFL tube (Cold Cathode Fluorescent Lamp) mounted to the LCD screen. The LCD screen needs the light given off of the Backlight.

Replacing the Backlight is a daunting task, and if done wrong, will cause possible damage to the LCD screen.

The LCD screen itself has a thin metal frame holding the components of the LCD screen together. This frame must usually be opened on the side that has the backlight, to access the backlight. The components that make up an LCD screen are fragile, and can easily be damaged.

The Inverter supplies power to the LCD screen, as well as the Backlight.
Inverters do go bad, but commonly it's the Backlight to go first.

This shows a typical Backlight replacement. It IS not an advertisement to attempt this yourself, but a reference tool for information.

My compaq presario 1200xl310's monitor remains black. I just purchased a new ac adapter for it. It had been unused for about a month. When I inserted the new adapter and powered it up---no screenlight-up....

You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

ACER ASPIRE LCD TROUBLE!!

If the screen appears dark with only a faint image or picture and the brightness can't be adjusted then it is likely that the screen backlight is not on - the backlight is like a very thin flourescent tube that runs along the bottom of the screen and provides the illumination. The backlight tube may be faulty or the small electronic inverter unit that powers the backlight tube may have failed. Occasionally the backlight is off because the little switch that is used to detect the screen lid being closed is broken or stuck in. If your backlight is faulty, some engineers will replace it - but it is more common that the entire screen is changed. If it is the inverter they can usually be replaced from ebay.
