Hi Guys, Has any one come across the flash/flash light not working on a iPhone 6s Plus? I have tried changing the power flex and restore via iTunes but still no flash. Any help would be much appreciated.

If you are confident that the replacement flex works, then you probably have a logic board issue. You might want to check the Strobe Driver (U3300). There are no filters on the output lines but there is one associated with the NTC (thermocouple), FL4720.
