You can read about on many other discussions on this Forum. First take apart the display which does not need any treatment, then drop the printed circuit board in a tray containing a glass of water and 3 tablespoons of vinegar cooking (I use the apple one). leave it for at least one day, then rinse everything under the tap and let it dry for another day, better if on a sheet of absorbent paper. Let us know Hope this helps Aurelio |
