1 month ago, I rinsed it for like 5 seconds under light tap water. The screen started flickering and then shortly shut off for 8 days before turning back on and functioning normally.
It has been fine for the past 2 weeks. But yesterday, the screen started flickering really aggressively again and it's very annoying. Knowing that the LCIs (Liquid Contact Indicators) in my phone are triggered red, I didn't take it to the Apple Store because they would charge me $800 CAD for out-of-warranty service.
I opened the phone up myself because I thought it was just corrosion on the display connectors, even after polishing the contacts on the display connectors, the problem still exists.
At this point, what is my best bet to get the problem fixed and over with?
Can I still take it to the Apple Store?
Where is the cheapest place to buy an OEM quality display?
What if I buy the display and it's actually the logic board?
Could it be firmware? (It happens on ALL screens)
