Did you perhaps install a CRT-OFF effect mod or do you have Jkay deluxe (and it's framework) installed? If you have installed a crt mod then have a look on the thread where you got the mod if it has a uninstaller. If you have the jkay one then deselect the crt effect on the misc settings of the deluxe settings app. You can also try updating to the latest stable kernel of boeffla.
