Missing component on logic board... Still functional?

Hello,

So after disassembling a destroyed iPhone and ripping one of the gps antenna leads I think I might have discovered a new issue..... I seem to be missing "DZ11" as referenced from another thread. Pic below to show..... What functionality have I lost or can the phone still function?

I am attempting to rebuild the phone using the "6 mini housings" that are floating around out there. The original housing and screen were destroyed and are unusable. Until the new housing arrives I have no way to test the phone.

zackven,

you've circled multiple components. DZ11 is the one to the right. It is a 6.8V-100PF Zener diode in a 01005 package. It is part of the dock connector circuitry and it is possible that your phone may still start but may fail in the boot loader. Replace it if missing or failed. Repair it once and repair it right.

This one has to do with sound and I think it is not "critical" in that sense but not sure what kind of functionality can be affected.

However, from he picture, I can't see it's missing unless it is not the picture of the actual board. Finally, if the screen and housing were "destroyed" he might have a lot more issues from hidden cold joints and cracks in and under the chips. Good luck, I wouldn't touch a "destroyed" phone.

Thanks for the comment! That is the actual board in the pic. The more I look at it though I too am having a hard time deciding if it is missing.... And I thought the same about the phone until I attempted to boot the phone with a replacement screen. To my surprise it booted right up and seemed to function perfectly. So with that test done I decided to attempt a resurrection for fun as I have never torn into an iPhone before. I have mostly stuck to the macs and iPads.

So the phone is back together and everything is functional! DZ11 does still appear to be on the board upon further inspection.
