So I'm having trouble with my Pinephone which only worked properly for a day and I'm trying to work out which part I need to replace. Today, I remembered that I had the hub that has HDMI output so I tried booting it with that connected with both the regular install (the preloaded plasma) and the jumpdrive SD card. Neither gave me HDMI output. So the question is, is it supposed to work from boot, which would point to the mainboard being the issue - or not, in which case, I'm still up in the air.
Just to forestall the obvious questions, the phone *is* technically booting. I can see output on the serial console, it gets a DHCP address etc, I just don't get any kind of display on the screen (though the backlight does come on). I don't *think* it's the software (though I'd be happy to be proven wrong) so I think it comes down to the mainboard or the display. I'd be happy to pay for either but don't want to shotgun things.
