mazenahmed75, Are you saying that the whole screen replacement procedure was done, with a charged battery still connected to the main board? If that is the case, you’ll have to try and dig out the schematics for your main board (if you give us the board model number, written on the main board somewhere, we can check). Then it’s a matter of finding the culprit in the system.

mazenahmed75, What you’ll have to do, is to disassemble the device and take out the main board and any / all daughter boards. This has to be done, in order to inspect both sides of the boards.

The schematics and board views are easily found online, but we don’t link to such here as it’s copyrighted material. If you should have problems finding it, feel free to reach out to me (my contact information is in my iFixit profile).

You need to inspect every component and trace on the boards under high magnification, in order to try and discern damage. If you can’t see anything visually wrong, it’s time to break out the DMM (digital multimeter) and start doing checks and measurements. This is where the schematics and board views come into play. Diagnosing is made a lot easier when you have the schematic, and having the board views even more so. The board views available should be readable with OpenBoardView, but I personally prefer and have bought Paul Daniels’ flexBoardView (FBV). FBV makes it so easy reading the board view files and references the schematic (assuming you have it).

Do a visual inspection of the board(s) and if you see damage, take good quality and up close pictures (good lighting!) then update your question with those: Adding images to existing questions.
