Jolla 1 HW parts placement needed
asked 2020-03-08 01:12:40 +0200
I have J1, cca 4,5 yo. After phone got wet (salty water), most of sensors (accelerometer, gyro, proximity, compass) stopped working. Also bottom light behaved strangely. Additionally some connectivity problems with the mobile network were observed. Charging worked fine. No battery draining was observed. I broke apart the phone (https://sailfishmods.de/inside-jp-1301). There was no visible damage to the PCBs. Did some clean-up and put everything together. The bottom light now works fine and it looks like troubles with mobile network have gone. Sensors still do not work. Here I need help. I assume all of sensors are in hermetically sealed chips, mounted on the main PCB. Unfortunately I do not have service manual and there is very little info on the net on J1 HW. Identifying where sensors are mounted might take lots of time - if possible at all, Any idea which part of PCB to clean, maybe some connector to check, maybe a service manual... I might go with a PCB bath in ISO-propil alcohol at the end.
Not worth the effort in my opinion, especially where sea water is involved.
Isopropyl alcohol won't do you any good, you'd do as well to bath it in WD40 to have any luck ridding the system of sea water, personally, I would accept that as a write off, fit for the bin!
