Hey thanks for stopping by. the problem i am facing is that the screen is very dim so dark that you cannot be able to see what you are doing. If you look close up you can make out the image being displayed on the screen. would this have to do with anything with the inverter, lamps or backlight? thank you.

Re: screen does not work
In most cases I would instantly say the inverter has failed. The fact you have an Acer I will say it hasn't failed, it's the electronics doing their job.
The problem you will have is failed capacitors and therefore the protection circuits have sprung into action to protect the remaining electronics in the inverter section.
If you know how to replace faulty/failed capacitors then it's an easy task. If not then I would advise your local TV tech do it for you. Repair wise, the parts are cheap, it's the labour that can get expensive. Going in there knowing the problem though will give you the edge when asking for a quote.

I would say either the video cable has disconneted, causeing the led that lights the screen up to not function,, simpley take the bezel around the screen, take the small screws aroud the screen to slightley pull the screen away from the back top to see if the cable is, or has pulled loose...If now the screen is bad..
Its the dynamic contrast ratio (DCR) that dims the display when dark images are displayed.
For my VA1926w, pressing the right most button (up arrow), enables or disables DCR. Keep this disabled.
This sounds to me to be a problem with the CFL tubes, soon they will stop working altogether and your diplay will be very dim, or may not come up at all. In which case if under warranty return it, if not you may need to replace the CFL tubes.
Dim or dark display can be caused by a faulty inverter board or faulty CCFL lamp. The inverter supplies high voltage to the CCFL lamp, the CCFL lamp is a miniture fluro tube and these dim with age.

You may have a faulty inverter or a faulty CCFL lamp.
A defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering 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 replacing the CCFL lamp. 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 and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net
I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.
Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life. First thing to check would be just that.
I had a similar problem with this monitor, mine was dim all the time to the point you cant use it, but the MENU icon was bright as new... also if cable was unplugged the box would float around as normal.... anyway I fixed it by taking it all apart and pushing in the socketed chip.. it clicked like it moved, I also pushed on the variable resistors on the power supply... now it works!!! First time since it quite working long time ago
