I just bought a Gateway MT6451 with a broken lcd. Ordered a new one, installed it and nothing. So I put the old one back in and that works. So I decide to test the inverter and backlight, both work. I then unlug the broken display backlight but leave the video cable hooked to the bad display, hook the new display's backlight to the inverter. power up... backlight works...so while the laptop is on I unplug the broken lcd video cable and plug it into the new one...it worked. But only till I reboot. I did it like 6 time and it worked that way each time. Oh and the vga and svideo ports work also. Anyone know why its not turning my new lcd on?
Check all usb connections i just fixed a emachine that seemed to boot up but no display would show lcd or ext. so i got to looking and one off the usb ports was broke and bent downt into the opening and shorting out when i removed it and turned back on it started booting up as normal

Re: New laptop lcd display not working
Check the panel to make sure the panels are the same model number there are more then one part number for gateway lcds for your model and if your laptop uses the xga screen and your not replacing with the correct panel then you will get the problem you are seeing now.even thought the inverter and back light are the same the panel are very differant.

This looks like a corrupted file in the boot section or a virus attack. the only solution is to reinstall the OS. there is no hardware error, if you had any hardware error the display will not be working fine. reinstall the Windows OS.

I have a new gateway laptop with windows 7 and today it said plugged in not charging 8%. I tried everything and nothing worked so I turned it off and unplugged it and took the battery out and put it back in and it started charging...hopefully this works.
vertical lines can mean either a connector problem on the lcd itself or on the motherboard connector or a problem with video ram or the chip. Unfortunately none of those are cheap or easy to fix. You can try an external monitor and if that displays normally then the problem is connector or lcd. You can sometimes find a replacement display at fair prices so if that is it then it might be worth fixing. If it is the motherboard then the repair can cost as much as a new replacement laptop.
It sounds like your AC cord or the female plugin soldered onto the motherboard has gone bad and will no longer make a connection to charge the battery or power the laptop on.
You would have to try a new power cord to find out which is the problem. If the cord fixes it, then it was just a bad cord (as you said it gets very hot, this maybe a sign of a cheap cord that has gone defective).
If the cord is not to blame, then the female plugin is loose and there is little you can do unless your an expert at soldering.

Unfortunately, you can't solve this problem. What I have learned as the tech working on a customers gateway mt6451 is that Gateway dropped the ball when they bought a cheap (they spent 5 cents instead of 20 cents) motherboard component that allows the adapter to charge battery and run the notebook without the battery installed, the component seems to have a 1 year if that life. I am surprised they haven't been sued or forced to extend the warranty (like HP had to with their dv8000 series notebooks) althought they would have to replace the motherboard with one that has an improved component on it. How do you sue a company or force them to extend the warranty for a replacement that is made with a better component?
Did the connector from the replacement LCD inverter fit in the socket of the motherboard? When you were replacing the LCD, did you have the battery out of the unit? And finally, have you attempted to start the laptop with the power cord in, but the battery out? I'm not familiar with the mx6931, but can you press the power on button without the trim piece that sits above the keyboard?
