I was given a Toshiba CF2750K that I knew used to work fine. When I got it home and turned it on, the top part of the screen was fine, but the bottom third, looked like it was squashed up and the bottom third of the screen is black. Since it was given to me, I don't really want to spend a bunch to have someone fix it, but thought I'd try and see if I could fix it myself (with help of course) LOL.
Anyway, if anybody could explain to me what's going on and how and if it can be fixed, I'd appreciate it.

Re: Help... LOL
It could be a screen cable fault. there is not much info on this model but would believe it would be the 2 cables on the lcd. if its the old tube type tv, when its been transported something could of come loose inside cable or a soldered part, to you would have a dry joint hope this helps

Unplug, remove battery, plug in reboot. OR, try a System Restore to a date before this issue. Have you cleaned the fan, vents, heatsink recently? Is it overheating? It would be helpful if we knew the Toshiba Model number and the OS you are using.

sounds like an irq conflict after trying to install projector. you will have to boot into safemode and go grom there. dont know what op system your using . windows used to be f8 on start up but thats changed now too.
THe screen on your laptop is faulty by the sound of it as the same processor is used for VGA out as the internal screen. Check the cables and connectors to your screen before replacing it. Consult a Toshiba Computer agent for confirmation if you are not sure.
Either the bulb has burned out or you have accidentally turned the control to darken the screen. Look in the top where the feet are stored. You should see a half moon shaped valve on the inside edge of the top front - that is the control for the brightness/darkness control of the screen.
Sounds like a virus/malware situation. Many of them are inactive until a network connection is detected. Try scanning your computer using Malwarebyte's Anti-malware and Grisoft's AVG antivirus. Both are free for home use.
the best thing to do is to get the help of a qualified technician(better go to a toshiba service centre) they will help you with this. try removing the battery after turning off the computer and removing the power supply.reinsert the battery and turn on th notebook. it should work fine. else contact the technician.
