I have just finished my second gameboy zero and everything worked perfectly until the screen remains blank during certain starts, then each time I start
Now the screen does not display anything but is on (backlight on).
I have re checked, in particular the connector of the lcd (640x480), re booted with the last version of circuit sword software, tested the circuit sword and all the leds status are ok.
Of course, impossible to display the "test mode" because the screen still displays nothing.
The power switch works very well, at startup, as at shutdown.
I can have an image in HDMI, but strangely it blocks on the loading of EMULATION STATION !!
Is it all related?
Perhaps you have a track to follow?
Thank you in advance .
