    What kind of 'pure' invertor is it? These are very rare- probably 98% are 'modified sine wave' since there is a lot of wasted power in a true analog sine wave generator.

    Have you checked the output voltage of the invertor? It may be affecting the ability of the plug-in and internal regulator to keep things within limits.

    The dc power supply failed and was fixed with a new supply cord, however it has now failed again, even tho the readings are 13+ volts. The 240 AC works fine and I want to instal a dedicated 240 AC supply

Check that the power adapter for your laptop supports 110V.
Measure the output power with a multimeter. If its below 110VAC (Alternating Current) your not getting enough power.

Does your computer work when its is not plugged in the Inverter?

I type slow, I have a Vizio M261VP LCD TV, I purchased it not working. I purchased a new power supply. A light comes on and flashes in lower right hand corner. I t does not flash on and off it flashes...


Good day sir chris!!!!

Welcome in fixya and I'm happy to work with you...

OK lets proceed to your TV problem..

The possible problem is not the power supply...There some shorted parts on inverter board,T-con board or main board so that the power will not initialize due to that shorted problem..

I teach you how to find which board is shorted or cause of that fault..

Just follow this procedure below.
  1. Open the back cover
  2. Look at the inverter board..it is slim board that have small transformer on it.
  3. unplug the inverter board first.Then try to power it on...
  4. If the LED on front of TV will not flashes from bright to dim it means you have shorted inverter board try to replace it..
  5. If the flashes remain..go to next step..Power off tv then reconnect inverter board,after that unplug T-con board..Then power on.
  6. If the LED on front of TV will not flashes from bright to dim it means you have shorted T-con board try to replace it..
  7. If all those procedure done but still problem persisted the only problem is main board..Replacing main board will fix the problem..
NOTE: When unplugging and replacing of all board make it sure to memorize all connection or its better if you take a picture on it for future reference..

Hope this solution will be helpful..Any rate will much appreciated..

Thanks for using fixya..have a nice day!!

My screen suddenly went black and even after turning it on and off, and removing the battery and holding down the power button the screen will not return to normal..help


Depending on the age of your laptop there is a good chance that your backlight inverter is no longer functioning.

What type of laptop do you have and how many years have you had it?

Depending on the model you might be able to pick up an inverter very cheap.

Power light comes on - numbers lock is lit steady, caps lock and scroll (I think that's what it is) flash. Screen stays black and then the laptop turns off...??


Can be one of three things:

Power not adequate enough for laptop - You can purchase a new power adapter relatively cheap from eBay for around $10.00. It may have been surged and will not allow the battery to charge or allow enough power to start the computer.

Bad battery - Take the battery out of the laptop and try it without. if it works, replace the battery or use without it.

Bad screen (inverter) - The inverter can be damaged. This can be caused by wear and tear, being dropped or other. The inverter is like a lamp that sits behind the screen. Take a flash light and place it directly into the screen to see if there is indeed a picture back there (will be very dim). If so, replace the inverter (difficult) or replace the screen (simple). Easier diagnosis would be to connect another monitor and see if it comes on (instead of the flashlight method).

HP DV1000 screen too dim


The 4 most common problems with dim lcd's on a laptop are boken screens, bad power inverter, bad florescent bulbs or a broken cable.

You can test the power inverter with a meter.

There should be 2 bulbs. If your screen is dim and your inverter is good and you can still make out what is on the screen, you probably have a bad bulb. If you can't determine which bulb is bad you'll have to replace both.

In my opinion, the easiest way to handle this is to replace the whole screen. Yes, it's more exspensive, but consider that it is most likely to fix your problem. A replacement screen comes with the power inverter, both bulbs, and the cable; already assembled and ready to install.

My dell e1404 laptop is having a issue with the screen. When you turn on the computer the screen will come on for about 30 seconds and then go off. When it's on everything looks normal. once it goes out...


The inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. The inverter board converts low voltage DC power (few volts) supplied by the motherboard to high voltage AC power (few hundred volts) needed for the backlight lamp.
When the inverter board works properly, the backlight lamp gets power and the LCD screen lights up. As a result, the image on the screen is bright. If the screen is dimming down, means that the inverter is failing in it;s job to supply the needed voltage to the Backlight.
The Inverter is mounted underneath the display screen and is connected by a two wire plug.

Acer Aspire 5735 LCD changes bight-dim-bright, etc.


You could have a faulty inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
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.

Hp laptop 9720us screen wont brighten or dim. last week my screen went blank brought it to a shop they changed the inverter and also some cable connection . works fine just not quite as bright as before ....


You got the wrong inverter fitted - i'm sure your unit requires a sinle lamp inverter and they have cheated - putting in a generic lamp inverter and branching togeather the wires to accomodate the single plug thus reducing the available volatage for the lamps - this is why it's dim - correct part is 431391-001 Display panel power inverter - For use with single lamp display panel

Acer aspire 5043wlmi laptop starts but know function of lcd but works on desktop monitor


The computer's power management system automatically dims the screen when using battery power, which is one of the power-saving features.
To adjust the brightness:
  • Hold down the Fn Key located at bottom left of your keyboard next to the Ctrl key, and adjust the screen brightness using the left/right arrow keys located at the bottom right of the keyboard.
If that's not it then

A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure. If your still under warranty then I would get Acer support on the phone and see what they can do.
An Inverter converts direct current (DC) to alternating current (AC).

Screen resolutio/brightness


Are you running on battery power or AC power? Some laptops are set up so that they will be dim on battery power.

Your battery could be going south on you.

The other possibility is that either your CCFL or inverter (most likely your CCFL lamp) is failing. They can be replaced for pretty cheap (part is about $5 to $10). The labor is a bit tricky but can be done if you are careful.
