    Alienware m9750 monitor won't work- Tried almost everything

    I put my computer on sleep, and left for a half hour, when I came back it was out of sleep mode, but the monitor was not on. When I try restarting it, I hear my hard drive, my fans kick in, the quick launch and power button, and the alien head, all light up blue,I can hear all the sounds when Windows starts up but the monitor doesn't show anything.

    Following the advice of google searches, I unplugged the battery, held the power button for a minute, and put it back in, and nothing changed. I then took off the bottom, unplugged + replugged the CMOS battery, which didn't work, and then I gutted my video cards and RAM, and tried with just the CMOS.

    Then I tried reseating the LCD cable and LCD inverter cable, which didn't work either.

    Plugging it into an external monitor doesn't work, the same problem happens and the external monitor reads "No Signal"

    Any help would be greatly appreciated, I might just buy a new computer considering how expensive I've heard repairs normally are. (And I'm off of my warranty)

    Thanks

    If you plugged it into an external, and it didn't work, I don't think it's the LCD.

    Never mind, I just read this and never saw that in his post.

    If it doesn't work on the external then it's probably an issue either with your motherboard or the video cards both of which will be hard to fix. If it's the motherboard then you've got virtually no chance of repairing it.

    I doubt there was anything better than stock. An entire M9750 on ebay is $800.

    There is only ONE motherboard that will fit in the M9750, and that's the one it was designed with.

    You can't put any other mobo in it.

    It's not like desktops where you can put just about any mobo in it within size and power limits.

    Even if you were lucky enough (and you'd have to be damn lucky) to find a whole M9750 motherboard on eBay that works, it'd probably cost not much less than an M9750 goes for on eBay (that works)
