Do the RG devices need a working SD card to display/charge?
I have an RG35XX Pro that doesn’t display anything (but you can see the display backlight on), I suspect the memory card is at fault. Is it normal for not even the charge symbol to display without an SD or with a corrupted one? Just so I can plan to get a replacement card if this is the behaviour by design. The LED status lights do come on.
Thanks in advance
