I have a Toshiba satellite laptop for more than a year, today I accidently hit on the back of the monitor really hard when the monitor was almost laid on the motherboard. After that I found out the monitor is not working anymore. Basically when I turn on the computer, only the top 1/4 of the monitor shows the correct color, the rest shows noisy signal and i am not able to see the monitor to even log in. I have quite some important files in the computer so I reallly need to repair this one. Could someone give me some suggestion on whether I could fix it by myself, or do I have to find a repair shop to change a monitor? Thank YOu!
