PinePhone Boots but only Shows Black Screen with Backlight - danyeaw - 06-29-2024
Problem: my PinePhone started only showing a black screen with backlight on, however it is booting fine
Events: I was listening to music when the display went black, and the phone continued to play the music. There was no update to software or damage to the phone.
Research: I have read posts on this forum, reddit, the Pine64 PinePhone FAQ, and I read the postmarketOS PinePhone wiki.
Software: postmarketOS v24.06 with gnome-mobile
Troubleshooting:
- I restarted the PinePhone and removed the battery
- I made sure the battery was fully charged
- I reinstalled postmarketOS using JumpDrive
- I edited the installation image to turn on SSH, the PinePhone is booting properly
- I checked that /sys/class/backlight/backlight/brightness wasn't somehow set to zero (it is 1567)
What I haven't tried yet, opening up the phone to check the display cable. Is this the next step? Is it possible that I have a bad display?

I heard on chat that the display backlight on, but black screen was a clear hardware issue. I'm going to try contacting PinePhone support as well.
