Got a badly damaged iPhone 8, was turning on NO IMAGE. Fixed by replacing c5706, Now getting a charging icon and an Apple logo but once the system turns on there’s no image… Only the backlight remains on
Es esta una buena pregunta?

This can easily turn into a rabbit hole especially if you start replacing components. For an iPhone 8 with this symptom I would first check the connector, it might look all right but I have been trolled by this once before. Have you got your iBridge yet?
Second from experience I would remove the CPU shield and check the CPU coils for cracks. Then put pressure on the CPU and see if image appears.
Remember the touch connector has a couple of image lines to. I would also check the proximity line as I have seen this pull the image down upon finished boot.
Finally check you are getting your display boost “PP6V0_DISPLAY_BOOST” Could be a problem with chestnut. Good luck.

Well, I don't have an iBridge yet :(
I removed the CPU shield and checked CPU coils, no cracks. Put pressure on the CPU still no luck.
Checked the proximity line too, looks fine.
PP6v0_DISPLAY_BOOST is fine, Chestnut is too.
Really confused on this one because never have I seen a phone boot with image and when it enters the system image disappears into thin air
Haha, I don't know but I'm a total idiot. Was looking at the intel schematics and did a jumper from the wrong location. All this while I was working thinking it was an intel board but it was a qcom board. and now i have fixed the image completely. Thanks a lot @imicrosoldering for your help always :D Really love the micro soldering community :)
