after replacing the rear case and front panel, Although it did not charging, I felt that electricity flows in hand while touching the screen. in addition, Connect the battery on the logic board and grab a rear case, a feeling tingling hands. Why electricity is flowing on the screen and rear case? Please help me, I really appreciate it.
I would start by checking the battery, battery connector, and see if they are damaged in any way that can cause them to make unwanted contact (short) with the board and/or back of the screen and/or back-case of the iPhone (especially near the bottom of the iPhone where the charging dock is located, and top of the screen where you have a piece of copper attached to the screen). Second, I would check to see if the board is damaged in any way where the connectors and screws attach or go through the board (and around them, again especially around the battery connector). I would also check if there are small pieces, grounding cables/clips that you did not place back correctly. The above is a start to try and find the reason for this “short”.. otherwise, may be someone who had a similar experience can pint out exactly where to look..
Have you tried removing the LCD?
