I was working on my raspberry over ssh, and then I lost connection with it.
So then I saw that when it boots the red lights turns on while the green light doesn't light on and there is no display.
Firstly I thought it was a power problem so I switch multiple power supplies and it didn't help.
Then I took a new sd flashed it with the newest raspian version and it also didn't help.
Then I took a USB drive flashed it with raspian and still it didn't fix the problem.
I have searched throughout the web and I didn't find other advice other than change power supply/sd.
What can cause the problem and how can I fix it?
Thanks for help!
