I have a raspberry pi 3 B that apparently stopped working after a thunderstorm. When it's plugged the red power led turns on but I can't boot the OS. I checked the voltage on GPIO pins and I get:
- 2.12v on 3.3 pin
- 4.7v on 5v pin
Also I checked the voltage across the polyfuse F1 and I get 4.7v on each side.
I noticed that when the board is plugged, the lan9514 chip becomes very hot.
What else could I do before throwing it away?
