I have a Toshiba L645-S4102, all systems are working, but my screen turns down the brightness and resolution when i try to maximize any window. Only the right side of the screen shows this low resolution problem but the left side is perfect. The problem appears exactly at half of display and the only way I found to correct it, is restoring my screens to minor size than maximized or close and open my screen a few times. Please help me. I can't find a flex cable for this laptop, usually that's the solution on most computers but i don't want to purchase parts I will never need or not solve my problem.

Check the display on some monitor through the vga port of the laptop whether the same is happening there, if its there then problem is of display driver, remove the driver boot the system then install it again, check it

You should be able to boot the computer from the operating system recovery disk. Most likely your harddrive crashed, or one of (many) other issues. It could have just erased your MBR, in which case you can boot with a live cd and recover most (if not all) of your data.

Try running the check disk utility.
To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r

You may have a faulty inverter, it supplies high voltage to the CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.
