I know there is a ton of topics "My raspberry won't boot" but I need to create a new one, sorry :) I simply didn't find the solution to my problem anywhere.
My Raspberry 3 with OSMC suddenly stopped working a few days ago - no internet (ethernet port was also "dead") and TV just showed "no signal"., but on the other hand LEDs were blinking both (it's a good sign, right? :) ). So I tried second SD card with a fresh image of OSMC and Raspberry booted without any problem. So I assume there must be a problem with SD card but after connecting it to my laptop it was mounted without any issue and fsck found just a few errors. But even after fixing those errors raspberry still behaves the same way.
Of course, I can simply reinstall the OSMC and it will (probably) work fine but I'm too lazy to configure it again. So I'll be happy for any help or hint. Thanks
