I have a DECT cordless phone which was dropped into clean water while switched on. After drying out, the phone seems to behave normally but the LCD display remains blank. The handset I a Panasonic KXA118EM, as supplied with the kx-tcd735em system.
Is there any chance that this might be a simple repair such as a connector needing reseating or similar? I've repaired oldish oscilloscopes and other stuff, but don't want to get into surface mount soldering.

It was two weeks ago, but I'll open it and leave it in a warm place, which should evaporate the water quicker.

I fear that that is 2 weeks too late. Water ingress into powered up electronics is usually fatal, even if the water can be removed very quickly after the event. The fact that it has been wet for 2 weeks may have allowed corrosion to occur which could permanently damage any number of components. The only solution for water ingress is to completely strip the unit immediately after the event and dry for several hours in direct sunlight or blow dry the items for several minutes with hot air such as from a hot air gun.
Having said that it may be that the zebra connectors
