What is this wire?!
So recently I've posted a question about my Z3 not giving any display despite giving sound and that I've replaced the LCD and the main flex cable but that didn't fix my problem.
People answered me as you can see that it could be the connector on the main board that is causing the problem so I decided to take the main board off and expect it.. I have found that the last person who fixed the phone has soldered some thin wire on the main board.. I don't know what this wire is soldered to or what is supposed to be connected to on its other end! I don't even know if this wire has anything to do with the display problem I'm trying to solve!
here is a picture of the main board with the soldered wire
Is dit een goede vraag?
