Chosen Solution

I have a toshiba satellite laptop. I had a cracked screen that i just replaced. However, upon turning it back on the new screen lit up for about 3 seconds and then went black. And then about a minute later the computer turned off. I tried removing the battery and trying that shift/f8/power trick but that did not work either. I am wondering what is wrong with my computer and how can i fix it. I am willing to try anything, thanks.

Alaina , Since you have managed to hook up an external monitor and it is showing up, I would say the replacement monitor is faulty or the monitor cable could be loose or damage. One more thing you could try, would be is to delete the laptop monitor driver and reinstall, if no go then you may want to open up the computer and recheck the installation of monitor, check the cables and reseat the connections, after this retry and if still not working faulty monitor, return for replacement/refund. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
