Turn off your pc and connect another monitor. If the external monitor works fine then the screen cable is damaged or your laptop's LCD needs replacement.

SOURCE: I have a samsung r620

Check whether is there a device that is emitting ay magnetic field (like a sub woofer or a speaker or a radio) that is interrupting the graphis card.
try connecting an external monitor and check whether the same issue is happening so that you can confirm whether the issue is related to the LCD of the laptop or with the graphics card it self and replace the LCD or the motherboard (the graphics card will be integrated onto the motherbard) accordingly.

Computer screen going staticky randomly during use, bright flashing colors.


Do a hard disk check. I would bet your hard drive is going on you. Make sure you back up everything. The other thing to check is your video card. Much easier to deal with on a tower than a laptop.

Probably a driver issue. Try Windows Update and select custom. Maybe there is an updated driver available, or there could be a driver conflict (wrong driver installed). At worst, it could be an issue with your screen itself or possibly even the motherboard. But I doubt it. If you can't find anything there, try http://www.toshiba.com

Keyboard randomly stops working


If this only occurs on battery power and your battery only holds a 10 minute charge? And your keyboard is external (PS2, or USB) it draws power from that battery (even the OEM keyboard does) and is probably glitching on you for lack of power. That's of course if I have understood you correctly?
Good luck.
