If the screen is unresponsive or you touch one icon and it lights up another one.
Before you all go fiddling with complicated calibration settings, try this simple solution with an old toothbrush:
Use a card or fingernail to slightly lift the screen bezel around the touch screen, only needs to be just enough to get a few toothbrush bristles under it.
Work the brush bristles gradually right around the screen and note what drops out on a clean sheet of paper. A few grains of sand / grit is enough to screw up your screen sensitivity.
Better yet, blast air under the bezel as you lift it. Use a can of air (as used for cleaning photographic lenses) with a fine nozzle attached. Now gasp in awe as your touch screen works properly again.
you may kiss my hand if this works out for you :smileyhappy:View original comment
