Hi Nick. First of all, thank you for your reply..
Welll.. I have some of these displays and they work properly but sometimes the LCD start to blink or become transparent and I have to push the metatic frame to get it working fine again... I have tested 5 or 6 of these 5110 displays and none of them worked 100%. Maybe I have tested ones from bad supplier or somehting like that.
Could you tell your 5110 supplier?
tks a lot
