LCD display faulty on Aastra 4223

[EndreMD]

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

@InIsp05- I don't know how to execute that upgrade you explained in your post

you can buy new lcd for all of that but after a time later again gone to faulty .... you must load all caa 1580026..1580027...1580028...1580029...1580048 to flash(tsw) or any folder(tse) and run upgarade.... first of all print cnbip:bpos=x.x.x; depend of your elu28..33 pos and let see what is the version of 422x
