Hello my name is Emre,
I live in Antalya, Turkey and being an Apple Technical Service for a year. First of all I want to tell you a short story of my bussiness today. I was working in tourism right before the pandemic period. But when the pandemic started my company fired me because their all jobs cancelled. Then I have tried to find something for myself to gain some money. Suddenly I thought I can buy & sell ipads and iphones to make some profit. But on the very first ipad 2, I got my first problem. Bought it came home and checked how to reset it to the factory settings (I wasnt using any apple before) I found out that there is an icloud locked there. And searched how I can get rid of it and found the ways with dcsd cables. Then I bought an ipad with sim card in it ( didnt have any clue about imei ) so another story started for me. So found the resistors there to remove (never done any technical repairs before except changing my bulbs at home) And with reading a lot and watching videos, Today I can fix mainboards of nearly all Apple devices But still having problems sometimes with troubleshooting of the errors. So this is enough for me and get back to the subject
I have my wife's A1707 macbook pro and ordered a battery 3 days ago. Changed it very well (I don't think that I have destroyed anywhere that time) but then I realised that macbook started to work so slow and did diagnostic and gave me PFM006 & PPN001 as everyone gets. But this didnt mean anything for me. So kept searching and found your video on youtube which shows kindly similiar problem. I have made an external mac os, run the hwmonitor and found only heatpipe incoming and outgoing air is around 128 degress. There is no damage on the card when I checked. I checked the trackpad and saw nothing there. Maybe Im missing of course something but really I couldn't find anywhere to look and Im totally new on macbooks. And the fans goes to the highest speed when mac os starts loading.
Anyone can show me a way for this?
Thank you in advance
Emre
Edit: I have checked the new battery with coconut app and shows good for the battery too.
Edit 2: Board has been tried with screen connector and trackpad connector plugged off and the result was same for both. And also Battery removed and same result. I have checked the voltages on R5390 and R5391 both have 3.3volts on their "1" pads.
Edit 3: I have took out U5850 & U5800 and desoldered them but nothing changed.
Edit4: Checked the voltages on U5820, getting 3.3v on 1,4 and 6 legs
