Note:   These units are known to develop faulty LCD Displays over time.   This is apparently due to poor bonding at the edges of the LCD Glass, which eventually leaks and the display turns black.   Once the damage is done, it is not reversible.

I noticed that my display started to show signs of 'blurring' and LCD leakage.   I used Bostik "Titan Bond" adhesive to seal the perimeter of the LCD display and this seems to have stopped any further degradation of the display for now
