iPhone 8 backlight working but no image Logic board repair

Hi,

I'm having an issue with iphone 8, back light but no display. I have a few questions.

 Can you tell me what readings I'm supposed to be getting at test points TPO533, TPO534 and TPO535? With just battery connected and phone on in voltage mode multimeter I'm getting (TPO533) 0.05v, (TPO534) 0.05V, (TPO535) 4.14v.

But when I switch over to diode mode I get (TPO533) 0.629v, (TPO534) 0.629v, (TPO535) OL. Does this tell me I have an issue on the TPO535 line? Or going by the volatge readings TPO533 & TPO534 Lines?

On J5700 I measured pin 5 supposed to be OL and got 1.5v instead. Then measured C5710 and also got 1.5v. measured caps next to them with same value and got 0.713v (C5715) and 0.672v (C5701) which both are similar readings. All measurements were taken in diode mode red on ground black on caps. Am i right to say that by this cap C5710 is bad?

 Also Pin 6 is showing 2.8v (supposed to be OL, maybe its close enough to OL?) and Pin 8 is showing also 2.8v and meant to be around 1.5v.

 All other pins are fine.

 Where else could I look and what do you think the issue could be? Any advice would be great.
