iPhone 6s LCD Backlight not working
I recently fixed an iPhone 6s after a fall into water using some isopropyl alcohol and an ultrasonic cleaner, after changing the battery the phone (almost) works, but there is a problem, the phone works without any problem but I need to use a flashlight to see the display because the backlight isn't turned on. My idea was to buy a new backlight panel and replace it because I think that the contact with water shorted it. What do you guys think should I do? Replace the back light panel or the problem is in some component on the logic board?
