speaker replace and no screen
#1
Hi eveyone!

I recently replace my loudspeaker for my pinephone postmarketos.
I use the Nokia N91.
https://wiki.pine64.org/wiki/PinePhone#S...ne64_store

When i start the phone, i see the green light showing up (12 secondes) and the screen doesn't display.
If i press the power button the black of the screen come more "light" and i press again to get it back to "dark" black.
No *tic* from the hardware when it boot. (like when starting the camera apps)
I can hold the power button to shutdown..

Can someone have any idea what i can do next?

Thank!

Use the serial terminal via the headphone jack to see what's actually happening during boot. Details are in the wiki

Thank wibble!

via the socat command i was able to see the boot process.
There is the "error" message i found..
