Hi Team !

Could anyone tell me please if it is any typical fault of Aastra digital 4223 phone's LCD displays ? I mean I bought a couple of phones online on the internet, all works well (in/out calls, function keys etc. are OK) but unfortunatelly all of them have LCD faults ( nothing appears on LCD display ). If anyone has experienced similar issues or have you any opinion regarding how could I solve this fault please advice me, I'd be grateful. Thanks .

You mean it wouldn't worth to change the display with a new one ? I'm wondering if the main board of the phone is faulty or the LCD ... I think I should try to change one display to see if it works. What's your opinion ? Thanks
