M5Core - blank screen
-
Hi, what kind of tests can I do to find issue with my M5Core? It was working ok for months. Suddenly it stopped to display on the screen. I can see its COM port, I can burn firmware in to it, I can send project to it but....nothing is displayed at all. Only thing visible when its on is backlight, I can also hear boot/on sound.

Can you install the latest firmware version make you are using Core for the Core1 gen and Core2 for the Core2/touch gen as they have different screens and are connected differently
UIFlow, so easy an adult can learn it!
If I don't know it, be patient!
I've ether not learned it or am too drunk to remember it!

M5Black, Go, Stick, Core2, and so much more it cant be fit in here! -
Did some tests tday with loading M5Core basic factory test project and checking what is coming out via COM port after restart...
and looks like "internals" are working, at the end of test when pressing each button it prints A B C on COM port monitor so it reacts to buttons press too but still only LCD backlight is up nothing else on LCD, i can connect to Core via usb or uiflow remotely still. -
