Have a problem that I can't solve. I changed the screen in my netbook after it was damaged on holiday - bought off of eBay but I matched the display numbers and am certain it is the same as the one removed from the netbook. Its a Toshiba NB550D netbook, with 4GB Ram, a Samsung 830 256GB SSD and windows 7 Home Premium 32bit. The installation was made by using the recovery discs I made from the original recovery partition and upgraded via the anytime upgrade tool. It works perfectly but the brightness controls now work in reverse i.e. increasing the brightness control in Windows actually reduces brightness. The same is true in reverse. It happens both when using the brightness function keys on the keyboard and when changing the brightness slider in the power settings. I've found plenty of forums with people having this problem with a variety of different laptops, different brands, where on changing the display that have had this problem. I've yet to find a fix. I'm not sure what's causing it. I thought it was something within windows that's causing this behaviour but I swapped on the original HDD with the original win7starter OS as shipped which also has the issue. So I have no idea what I need to do to fix it. Any ideas? Obviously it's a minor issue and I can live with it as it is but would like to get it working correctly again.
