Why is my flashlight not working / very dim after phone repair?

Hi all,

I just took my iPhone 5S almost completely apart when I replaced the charge port module. I tested everything when I put it back together and I'm pretty sure everything worked properly... But then a day or so later, I realized the LED flashlight isn't turning on when I activate flashlight, and when I take a picture with flash, the LED flashes very dim.

What could be causing that? It's odd that it works at all as I'd expect to either work or not work rather than be dim.

Cheers,

T

Do you still have the old charing port. If so put back in the iPhone and see if the flashlight works if it does then you know the charging port you replaced it is defective and need to replace it under warranty.

I've had a very similar / weird experience over the past week...

So, I needed to replace a broken screen. I did that and I noticed a couple of days later that the flashlight wouldn't turn on in the Control Center. Also, when I take a photo with the flash set to "On" it does not fire properly... The bottom yellow / amber flash fires but the bright white flash does not... I tried reinstalling the screen several times but no go...

Several days later the screen started to act up (touch was misbehaving) so I managed to get a replacement. This time, I was real careful, I hooked up the 2 screen ribbon cables (touch + main LCD) and turned it on. Booooom the LED fired right up in Control Center. Awesome, I built up the rest of the screen and assembled the phone as normal, turned it on, NO FLASHLIGHT. Shiiiiiiit tried all sorts, nothing worked so I gave up.

A week after that, the replacement screen was also began to act up - same touch issue. So I bought another screen from another seller... Tested the flashlight again and it worked fine. I built the screen / phone back together and the same issue again, the flashlight WILL NOT WORK. I'm usually pretty good with these things, I've repaired dozens of phones, laptops etc. and I cannot work this one out.

Is it possible I am shorting and killing something in the LCD when I've reassembled the phone? All 3 screens (2 of which have touch issues anyway) will not activate the flashlight? But I know at least 2 if not all 3 of them did fire up the flash prior to rebuilding the phone?

I've tried connecting the bare screens again with no earpiece / proximity sensor ribbon connected... I've removed the camera... I've done soft / hard resets, new phone restore, back up restore - nothing makes any difference... no flashlight.

So, it's either something I keep damaging in the screen with each replacement or it's a very weird iOS bug?

Any advice / help will be hugely appreciated - thanks in advance!
