if this is only just happening without any drop etc, it may be the beginning of the end for the screen. See if a restore etc helps, clean the connection for no.1 with a little isopropyl alcohol to make sure its not old corrosion going on. If it still persists then I'd change the screen (LCD)..if it still there after that then could be the coil for backlight being silly. Try one thing at a time...
