Gateway 450ROG backlight not working

The backlight is not working but everything else is, I can faintly see the screen. From searching I know it is the light or the inverter. When I open the monitor I don't see the bulb, where is it located? Is there a way to tell if it is the inverter or the bulb other that part swap? Is there a link for a diagram? Any help would be appreciated - thanks.

Where is the backlight button on a netbook gateway atom N455?


I think there is no backlight button in any lcd monitors on any laptop. If it's dark, time to buy a replacement lcd screen.

I have a Gateway 450ROG with very dim video on the display, I can hook up an external monitor and the video on the external monitor is fine but still very dimvideo on the monitor of the laptop. You can...


Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

What Would Cause Really Dim Video?


This is most likely either the inverter or the backlight. In the following web page they describe how to troubleshoot an inverter:
http://www.fonerbooks.com/test.htm

Here's an excerpt from that web page:

When the external screen works, the cabling all appears good, and a very faint image is apparent on the laptop screen, you know that the backlight isn't lighting up. Not only is inverter failure more common than backlight (CCFL lamp) failure, but inverters are easier to replace. And now that it's winter, keep in mind that temperature has an affect on the voltage required to get the backlight to strike, so if the laptop has been sitting in a freezing car for a while and the screen doesn't light up, don't rush to take it apart. Give it a couple hours to warm up, but don't do anything whacky like sticking it in an oven or on a radiator!

If you google YouTube videos, they have some on laptop repair, and describe the disassembly process.
Good luck, and hope this helps.

Gateway 450ROG screen went dark


Try using a can of compressed air and blowing out all the nooks and cranies. I did this and it worked for mine. Haven't had a problem since doing this. Let me know if you need more help.

Gateway laptop wont display my desktop -screen is black


Does backlight stay on, or does it look like the screen is turned off? If it looks like it is turned off, can you look extremely closely and see your desktop if held in good light?

Laptop screen very dark


the screen is not a sealed unit... and the backlight and the lcd bulb can both be changed out...
I do it on a daily basis....

It is way cheaper to change out the lcd bulb than it is to replace the lcd display panel... Way CHEAPER

the results are the same

Without a visual inspection it would be impossible to say. But it does sound like you will almost certainly need a new motherboard.
