LEDs turn red then green(solid) as expected but screen doesn’t turn on at all. All worked perfectly until I wanted to test Manjaro i3 from SD card. I have Manjaro KDE on eMmc installed already. Ok booted Manjaro i3 from SD card all worked fine. I updated this distro installed a few things from repository and built Vivaldi browser from AUR using Parmac. Then when rebooting I got the issue above. I thought there was something wrong with SD card and ejected and re booted only to see same issue with my installed system - nothing boots. I tried to charge in full then let it go completely flat in case of some endless sleep cycle ( this took about 20 hours). Any suggestions why the screen is just completely black? I know very little about things like gpu etc. so don’t know if any faulty hardware is preventing something to start screen? I’m really at a loss - I haven’t touched the hardware inside I have only flashed a card. SD card 32 gb and worked fine when I had Debian and Manjaro KDE on card. Any ideas??If you are seeing the green light, the machine may very well have booted, but has some kind of display issue. As a first step have you tried re-writing the sd card with the Manjaro i3 that originally did boot and trying to boot from that? IF that works you know it's a software problem...
Also, have you tried using the f2 key to turn up the brightness? ..in case somehting in the update turned it down......
I'm assuming you don't have a serial cable. it's very helpful to have serial output at times like this. You can watch the booting sequence and usually can see where the system is hanging or failing. Often, if its something like a software display problem, you can fix it....
Hey there thanks for your response - Good idea to re-write the SD Card with a Manjaro i3 as a known system - What I have done so far is downloading and writing Debian (Mr. Fix it version) that the PBP came with only to get the exact same - red LED few seconds then solid green. I have tried all key combinations as you suggest but without any change (also though perhaps it was set to external monitor for some strange reason). Thank you so much for suggesting the serial cable - I don't have but strongly considering buying
