I’ve replaced the screen on my Iphone 6S because it was broken. at first all seamed fine but after a few minutes i couldnt get my screen to turn on. i Researched and i found out that it could be a blown backlight filter. The strange thing however is that when im charging my phone, or when i start it up again after a hard reset its showing the battery sign or apple logo with full beam. Do you guys have an idea how i can solve this issue?
Either you have a defective screen or the backlight circuit needs to be diagnosed and fixed by someone that does microsoldering / board level repairs on iPhones.
