Hi folks,
my FP1 second batch doesn’t start anymore. It keeps a black screen, though the Led blinks green in longer intervals after pushing the ON button. First, should this blinking tell me something?
What could be the problem?
Short history:
I changed the screen about six weeks ago. Then I had the issue with the proximity sensor, the screen turning black whenever I made calls. I used the workaround “start button ends call” for a while now and now tried cleaning the proximity sensor. Without sucess.
Instead it didn’t turn on anymore. Re-opened, checked for loose connections inside. Then i noticed the green Led after pressing the ON button for about three seconds.
Are you talking about a FP1 or FP2? Anyway, does it boot if you attach power to it with the charger (usb cable) and if you keep the battery in at the same time?
That sounds entirely possible. I still suspect it has to do with the proximity sensor that failed earlier.
Or the screen isn’t hooked up proberly - i mean, it’s a new replacement part, and it worked before, but the bug with the black screen started after installing it. It feels like a hardware thingy, but in the meantime i opened again and doublechecked. Which connection is for the screen? probably the big on the mainboard? - it sits sort of loose, so i don’t trust it to stay on when i close the phone.
Thanks for all the replies so far. Problem is anything but solved. If anyone has further input or experiencing the same problem i’m delighted to hear from you.
I would open it up and recheck all screen connectors (the “flat ribbon” cables). Also check if you can “talk” to the phone by using adb (if you had usb debugging switch on before …)
The cable must not be loose. I have had this problem before and I had to push a bit more than I’d usually dared. The connectors are tough to get back in place sometimes.
I re-re-checked the wires. Either they’re broken inside, or the connection doesn’t seem to be the problem after re-re-checking. Gave it a thorough push. I’m close to giving up. Tomorrow I will get an IPHONE from a buddy because I actually need to make phone calls. Everybody has their own reasons for not having an Iphone, so do I. My love affair with fairphone was intense, but short.
The advice about adb looked interesting, and I’ll experiement into that out of sheer interest, but I hadn’t switched usb debugging on, besides I doubt it’s a software issue.
Yep, but if you can talk to the phone … it would mean that the screen might be the “only” problem. I’m sure you know/used/checked the ifixit guide already. What ever you will do next … all the best!
