SOURCE: hi i have a dull screen on my dell inspiron 6000. i have replaced the inverter and replaced the backlight but still dull. is there anything else i can do?

Maybe your problem was the Video Card. Did you try an external monitor before you replaced the inverter and backlight? Try an external monitor and if it does the same thing then the Video Card is bad.

My Vizio GV42L is fading to a dull whitish color after 2-3 minutes. I can still see the TV program I am on but the screen just goes to a dull whitish color. No boxes or anything popping up. Basical


Either its back light inverter board, or, the LVDS cable has the fault. First try by re-seat the LVDS cable, and check. Thus you can make sure about the fault. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic /Timeslide, can be selected by the drop-down list, by the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

Screen on laptop advent 7102 very dull can hard use it hardly any brightness


The LCD screen for the Advent 7102 does not produce light. It needs an additional light source.
A Backlight is the additional light source.

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

An Inverter (Screen Inverter) converts electricity from the laptop, for the LCD screen, and the Backlight.

90 PERCENT OF THE TIME the fault is the Inverter.


The Inverter is a small circuit board located behind the Display Bezel, and under the LCD screen.

[ The Display Bezel is the thin plastic frame in front of the LCD screen. Resembles a picture frame ]

My Fujitsu laptop's screen is dull but i can barely see the desktop icons.what could be the problem?


The screen displays is dark/ dim because there is no backlight.
There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both. But most likely it is the CCFL (Lamp). Its life is limited and depending upon how long it has been in use, you can have a better idea - if its the CCFL or Inverter.
(Rest assure that your system is ok and you can check it by connecting you laptop with some external display, which would work fine)
So, my advice is that you get it properly checked by any professional for replacement of Inverter CCFL.

Hope it helps! Good Luck!

DISPLAY SCREEN VERY DULL/DIM


if you have tried adjusting light level without success may be hardware problem - may need to replace either the backlight inverter or backlight lamps (2) as either may be dying

Mitac 8060b screen is really dull can only just make out any detail on screen has anyone any information as to why,thank you


Try attaching an external monitor to the laptop & see if you could get any display on it. If this is successful, then you might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp

LCD is dull....


Try to connect the machine to an external monitor and see if display is ok or not.
Also, try updating the video driver and check whether you have connected the LCD correctly to the laptop.

I've acer travelmate 4500 laptop. Till yesterday it was working fine, but today i donno what happend to it.. the screen display is completely dull. that I couldn't see the display and if I closely observe...


The possible reasons is that you have turned down your brightness and contrast without realizing it, to fix this simply look for a brightness key on your keyboard and turn it up. If it is missing or did not fully work, see if you can notice any image and try to get into your Display properties, click the setting tab and go into advanced and turn up your brightness and contrast from there. If this does not work, im afraid to say you have damaged your LCD screen and this would result in your dull screen appearance. Get a computer technician to take a good look at it to see what has happened if this is the case

Hope This Helps

Hi,

If you have getting dull display it's a inverter problem in laptop.or if you not getting no display(screen) then two types of problem in your laptop please try to solve that problems.

  1. Please check RAM is working or not.
  2. If RAM is good then it's a Mother Board Problem.

Thanks
