Display goes blank. Clicking sound on line.
Replaced the Adapter a few years ago which solved the problem but not this time. I notice the new one heats up now and has not solved the problem of the display going blank, and a sort of sporadic clicking sound when I pick up the receiver.
I am able to make and receive calls.
Could the motherboard be the problem?
How can I diagnose this problem, get the parts I need, and from where?
Appreciate any help before I just throw it away!
