Question about Sony SPP M920 Cordless Phone

it acts as if it cannot see dialtone. Try pluging in a known good working phone and cord into jack. if the known good phone works try just replacing the cord. and so on until you find the faulty element

The problem is in the main base, the cordless phone is unable to communicate with the base because it has stopped working that is why you are getting the four beeps. It is more cost effective to replace the complete phone system than repair. The only other possibility "and it is long short" unplug the power and the phone line cord from the wall and let it sit at least 30 minutes, this might reset the processor ic and get your system working again.

If you are getting fragments showing up it is more than likely the driver ic or the display chip has become defective, you are further ahead replacing the phone because it is not a cost effective to repair let alone trying to find parts for it.
