iPhone 11 Pro Max water damage - no image, broken battery connector - advanced motherboard repair

Here we have an iPhone 11 Pro Max with water damage, broken battery connector and U4100 ripped of from the board. It was in another repair shop that took of some shield (randomly).
They were very close to find the problem with the image, because they took some measurements on the screen connector.
Display was also bad, had a short on PP3V0_DISPLAY_VCI_CONN.
Some of the tools and supplies i use all time
- Sugon T26 soldering station with JBC C210-018, C210-002 and C210-020 tips
- Gordak 952-A (I'm using this only for it's soldering iron)
- 8858 Hot Air Station (no name)
- Seek Compact XR Thermal Camera
- Sunshine DT-17N Multimeter
- HY3005D Power Supply (very old)
- Kingbo RMA 218 Flux
- Baku BK-227 Flux
- Cynel Soldering Wire 0.5mm and 0.7mm
- Mechanic XGS40 158C Solder Paste
- Relife RL-404 138C Solder Paste

[@PhoneRepairRO]

Hello,
Your problem might be the display. It's clear white or has some dots on it? If has dots on it, it might be from cpu.
Have a nice day.
