Hi y’all!
My raspberry pi 4b won’t display anything when I try to display it on a monitor using hdmi. On my TV it will flash the Raspberry logo turning on but then immediately turn off and say no signal. On my monitor it doesn’t display anything, my monitor says no signal. I know for sure my power supply isn’t the issue.
I thought the sd card was corrupted but when I plug it in my laptop using an Ethernet cable, it works on Linux. So I’m guessing it’s not since it’s still working just not displaying?
Could it just be a video display issue or is it possible for a corrupted sd still work on Linux ( I don’t think so I just want to make sure)?
I’m pretty new to raspberry pi so I appreciate any help and tips! Thanks for reading!
"Could it just be a video display issue "
Yes.
"I thought the sd card was corrupted [ ... ] is it possible for a corrupted sd still work on Linux "
A very wise 'mainframe' maintenance engineer taught me - about 50 years ago - that while it is possible to predict the behaviour of a system that is working to its specification it is not safe to make any assumptions about the behaviour of that system if there is a possibility of failure.
What evidence do you have that the microSD card is corrupt? Whether or not it still works partially under some circumstances will depend on the random impact of the corruption.
If there is any doubt, put yourself on a firm foundation by installing a freshly downloaded image of RasPiOS onto a new good-quality microSD card.
However, my hunch is that in this case the issue is an incompatibility between the TV/monitor and the default video configuration of the unspecified Operating System on the microSD card.
