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.

How do i brighten mytouch screen it looks dull gray? the light use to be brighter in the background know it seems to look dingy and graish not bright it looks ike a lightbulb went out and it makes it...

The dark screen with faint, hard to see display is due to the failure of (i) CCFL (Cold Cathode Florecent Lamp) OR LED, which is the back light or the (ii) Inverter board, which provides high voltage to the CCFL. So, it is recommended that you get it properly checked by any professional for replacement of CCFL/LED.

Also, refer here to my earlier solution to a similar problem, which was rated as very helpful

GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

HP L1720 flickering!

this is common, the display is bad.
all displays, fail. all do. no reason to get angry,
a broken display is worth nearly zero value $0
so how much money will you spend on worthless.?
you can get a new display at Walmart for $65, ,
lines are usually very serious. and is not ever the DC-DC inverter
a bad inverter (< it's power supply) is for the back ground lamps. not data side. the data side is failing and is common, if you twist the screen
it gets worse. ? bingo. data driver connections bad , screen.
IN most cases the part that is bad (screen), costs $100 new. or 50 used
why go there/
?

My Dell Inspiron 6400 is extremely dark. +brightness does nothing

Hi there.
Yes, if you can see a very faint image on the screen that indicates that the inverter or inverter coil has become defective and needs looking at or replacing.

Good luck and thanks for using Fixya!!

Pfaff 7570 display screen info is very faint & difficult to read

Hi Carolyn,

Look for a small turning wheel, just below the green and pink selection knobs, on the front right of your machine. Turn it anticlock wise for a darker image and clockwise for a lighter image. Enjoy!

The screen won't light up and when the screen slided up the screen display becomes too bright (white) that nothing can be read off it

My MDA loses its settings frequently as well. Go to Start, Settings, System, Backlight, and see what it looks like. Maybe the settings have changed.

Starting up programs affects screen visibility

This would almost have to be a video driver problem. Try the WIndows default video drivers for some common settings (like 1024x768) and reboot and see if this fixes it. If it does, the problem is video drivers - download the latest from the web and install them.

If this doesn't fix it, try reinstalling the latest version of DirectX. Also, try stepping down VIDEO HARDWARE ACCELERATION through the video settings display panel. Finally, if it really only does it when you run a new program, as a last resort, you can try to reinstall the operating system from scratch and install the latest drivers from the laptop manufacturer.

Good luck...
