Phone won't start or show sign when charging

Hello all.

S6 Edge won't turn on. When charging, no led is on. When I force the hard reset with the volume and power buttons, i get a blue led that will stay on for days and nothing happens on the screen.

Then everything is off again and back to the beginning of the message.

Any idea what I need to change? I've had it for 3 years and never dropped on floor or water.

Please advise.

Regards
