iPhone 5 water damage no life no screen

i got the following problem....



cleaned with alcohol 2 times the whole motherbord... tried different screens... different accus... still no apple logo or what else : ((((



also i checked between pin 1 and 4.. there is a huge resistance... so no short anywhere...



tried to connect with: motherbord - new dock - screen(working 100%).... also Nothing (((

i can feel that under the shield its getting warm...The hottest place is behind the nano-sim on the back...



Really frustrating!!!



What can i do now? Do i need to clean under the shield? But how am i going to open the shield? Because it is soldered everywhere...:confused::confused:
