My L009 struck by thunder and no more booting although power light is on. I used another L009 power adapter and yet no sign of booting. What should I do?
It’s probably dead. You can try to replace magnetics (transformers) and see if it helps. Ethernet is rated for surges of up to 1500V, so it’s possible that the magnetics themselves died and saved the CPU from getting the bulk of damage. Also try the serial console to see if it’s alive.
Try to netinstall as lights are on and there is a tiny chance that it could help but lightning usually implies at least a coma for a device 
@BartoszP I have not thought of that, I will try that soon
I will try that and see if I can get it back to normal. Thanks
