Screen keeps blank, when inserting the power, the speaker phone button lids up with the 2 buttons on top of it. then the line buttons lid up orange. after a few sec the speaker lids up again. and then it goes in a loop on and off.
Thanks for taking the time to reply, and trying to help me..
How can I be sure that its an hardware failure? If yes is there a way to repair it? maybe buying some parts somewhere? support told me its out of warranty...
