i hope you guys can see the image that i attach. ive been trying to repair this phone , all shops try to change the LCD , but it not working ( all black screen when the phone turned on) the shops try 5 unit new LCD. all pitch black upon start. when i get the current screen back on , the screen is turned on - but flikering all over the places. unresponsive to touch. i might not be the LCD that is broke? but why the new LCD not acting like current LCD (can be turned on - but flikering - unresponsive ) new LCD that the repair shop replaced are pitch black upon turned on i hope you guys can understand my potato explaination. thanks in advance.
If replacement screens do not fix this problem then the problem would be either the LCD display connector on the board or something wrong on the image display circuit on the logic board. Either issues require micro-soldering which is what reputable repair shops can do if they do board-level repairs for iPhones.
