Sold an iPhone 6 to a customer back in May. It’s back in our shop with no display on screen. The phone is dectected by iTunes and in recovery mode but even with a restore still no display.
I have tried other lcds and problem persists. From my experience it doesn’t seem to be a backlight, nothing at all not even a dim sign on life on screen.
Thanks
Is this a good question?

Check FL2027 PP1v8 for 1.8, FL2061 PN5V7 for -5.7, FL2037 PP5V7 for 5.7, FL2035 (LCM_CHESTNUT_PWR_EN) and FL2036 (AP_TO LCM_RESET) for 1.8 with screen connected as well as FL2050 (PMU_TO_PHOTON_ALIVE) for 1.7 - 1.8

This is almost certainly long screw damage tearing lcm_pwr_en or reset lines since that is the common fault for no image iPhone 6 I. The absence of water damage.

What would you suggest as my first step? BTW... love your YouTube channel.
Watch my video on using diode mode to determine any fault and then you tell me.

Try using a flashlight to make sure it's not backlight. After that I would guess the cumulus on that weak iPhone 6 frame

You have tried other lcds, so it may be the motherboard or connectors.

I have this same issue. Trying to fix my father’s iPhone 6. He jumped into a lake with it.
The phone will turn. It’s detected by iTunes when I plug it into my Mac. I’ve replaced two different displays and each one doesn’t work. I also tried those display on another iPhone 6 and they work fine. So, I’m ruling out that I need to replace the screen.
I think it’s something on the logic board, but I have no idea what. My guess is that I need to replace the LCD IC. Has anyone ever done this? Should I explore other suggestions? Really need your help.

How to fix no image / black display for iPhone 6

The backlight driver is underfilled and heavily protected from water on the iPhone 6. That is not a failure point for water damage—you have a long road in front of you if you want to learn microsoldering and diagnostics to bring back backlight in a wet iPhone 6, but it is possible.
