Gateway 450ROG screen problem

The screen on the laptop will light up but nothing else. We hooked up another monitor and it works. We assumed it was the screen so we ordered another screen and it still will not work. Just lights up but no blue, black or icons, nothing. Just a lighted screen.THis happened after ejecting a DVD. Got any ideas?

This could be the inverter, or screen cable. Try replacing the cable first.

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.

Gateway 450ROG, will not start. Red DVD/CD ROM


I have the very same problem, the Drive light turns red, the screen is "black" and the battery charging light indicator on the front is off. No differance if I'm traying to power up on battery or AC-adapter.

Before this problem appeared I had problems where the laptop was powering off, with no warning, and I had to restart it. This happened several times and was going on for about a week before it died totally. Can it be the CMOS battery on the mother board? Anyone having clue what the problem could be?

Gateway laptop 450ROG video issue when using a projector


Honestly from the information you have listed it sounds like the issue is with your projector, not your laptop. If your laptop was having display issues it would be consistent on anything it was attempting to output display to, such as your monitor.

The projector sounds like its out of focus and possibly has a bad back light in it, I would suggest contacting the manufacture for a possible resolution.

Try hooking the Laptop to an external monitor like from your desktop pc,,you can see the connection on the back of the laptop,,When you do this, and you can see Windows on the Desktop monitor,,then this would indicate that your Back light on your Laptop screen may have burnt out .

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

Gateway 450rog does not power on


Sounds like a voltage regulator. Have the system diagnosed at a repair shop. Sorry I know this isn't what you wanted to hear, but is probably the correct answer.
