Chosen Solution
Hey all, I just fixed the power/lock button on my iPhone SE by taking it apart and cleaning it. It was sticking. I also swapped the battery while I was there. I took the logic board out first before taking the battery out so as not to cause any pry damage. After reassembly, everything works great and as it should except the flash. When the torch is activated from the pull-up Control Centre the flash blinks quickly for a split second (not at full brightness) and then remains off. Any idea what it is? I was very, very careful with the cable that contains the power/lock, flash and volume controls on it. It is not ripped or damaged. Here is a photo (as clear as I can get) of where I lifted the logic board from so you can identify any damage or anything.

Get yourself a good light source and some magnifier and check carefully the connector on the logic board, on the SE series the cable is somewhat difficult to fit in place and the socket gets easily damaged, it’s a bit more pesky than other iPhones. I’ve seen many with the plastic part deformed. It can sometimes be “carved” back in shape with lots of care. Yet you might have received a faulty replacement, that’s always a possibility with aftermarket parts.
