Front camera isnt working but earpiece is.

Hey all, i made this account just for this question since i cant find any help for it, i have this 6+ with me that i replaced the screen for, the rear camera and the front weren't working earlier, so i opened it thinking it might be dust or something, used some canned air to clean it, and put it all together. The Rear camera did work just fine afterwards, but not the front one, so i do some quick research since its getting hotter than usual on the cable side where the screen plugs in, and i guess a cable isn't working right, or "shorting", so i order the whole camera cable, plug it in, but no luck, still not working, earpiece works though, but gets hot on the same spot, i take the camera cable off, and its not hot anymore, but of course no camera, What could be the reason behind it not working? i tried different camera cables, but nothing works, can the rear camera mess up the front one since it wasnt working and somehow started working again? or something? im completely lost.

Thank you :)

It's just a shot in the dark, but sometimes when people remove the flex connector from the board, you can knock off little component(s) from the board that sit right next to the connectors...

Or dislodge them from the board enough to where they do not make contact.

Check near the connector to make sure this isn't the case.

I tried doing this, but ill be lying if i said i know what im doing, i have a multimeter here , but again, i dnt even know what im supposed to look at or how to use it. Is it possible to have something else that can interfere with the camera ? like another faulty cable maybe ?

의

It is possible that it could be something else, but doubtful that it's another cable. It's really hard to guess without seeing it and testing it . As far as using your multimeter to test it, I could walk you through it or you could watch a video on how...it's pretty simple...but they are extremely tiny and the tips on your multimeter wouldn't work and you'd need a microscope or good magnification to do it. Best thing I guess I could suggest is taking it to a good Microsolderer to have it checked out. Sorry I couldn't be of more help

의

I definitely don't think it's the cable. Two in a row is a bit tricky. I mean it could be. I think you're on the right path though, @teetopp01 check the board to see if any components have been damaged around the front camera fpc connector

의

@teetopp01 @theimedic i guess ill have to make some more research into it, but lets say there was a problem with the board itself, what are my options to fix it? im guessing it would be risky for a beginner to fix? should i forget about the phone and use it for future parts if there is a problem with the board ?

Thank you all for your response, i appreciate it.

의

@casgan, The board can most likely be repaired and wouldn't trash it or use it as a parts board. If you can get it to a good repair shop that does microsoldering, I am sure they could figure out the issue. When you took off the shield and cable flexes, did you make sure to put the same screws back in their same holes? Each one is a different length and can cause what is known as "Long hole damage" if you did not it can damage traces on the motherboard.

Have you tried cleaning the connector points where it plugs into the logic board? It may not fully be seated or a pin or two could be broken, and getting hott because it is not fully connected,
