[Kreg26]

i have a d500 that when you turn on activates the flash for the camera i have never come across this fault before and was wondering if anyone had any ideas on how to repair this problem?????????????
it only started after changing the screen by anoother company.....

your phone possibly has liquid contamination causing the flash to short
