Connector/socket system    Display Problem Come From- 1. Display Damage/Broken/ Broken Microchip area in  display2. Flex and parts damage3. connector damage on both (pcb and display flex)4. wrong software.5. Display line broken from display connection to CPU.6. CPU internal display section Damage.    1. Display Damage/Broken/Broken Microchip area  in  display For this type of problem, have  no way without  display change (every one know it). so justchange display.Display Microchip area on display panel-2. Flex and parts damage Sometimes we can see with our won eyes where is  broken flex  line or any parts. but maximum time we can't see it normally. so we try to repair our   display, when we confirmphone show display problem only for display panel not for any type of   pcb defect. can we confirm it by replacing a good display on pcb. when we 100% confirm   problem only on displaypanale than we can try to repair it. otherwise first fix other problem. For this type of problem can you repair flex cable with extra wire, but   first need to calculate flex cable all line with multimeter. some times line cross   flex cable 1 side toanother side by in flex. so check them. and you try to change this type   or parts, see picture-here i mark some parts and only one type of display,   other display parts find by your self. though possible, change all parts from another display (which is broken   but parts is ok)    3.  connector damage on both (pcb and display  flex) Connector/socket system display create problem from  there  connector. so check simpaley thereall line with multimeter and fix them. though need join them with extra   wire from direct pcb to display. also you can change both socket.    4. wrong software for wrong flash file  or software problem we face  white screen problem. so take any step  beforedo 100% Confirm its not for software problem. we maximum time face this problem after flash or format. so after flash   or format when a deadphone is power on. we can 90% confirm its for wrong version flash file.   so first see your original flash file version than backup it and next flash phone with   this same version new/another ok file.   5.  Display line broken from display connection  to CPU. 98% china phone display line going direct cpu and  other 2%  have display ic. and sometimesdisplay line broken or break soldering from cpu to pcb middle point.   just cpu bad soldering. so can you try to re-hot cpu with your won risk.also sometimes pcb internal line broken from cpu to display connection   point. so check them and fix them. (but do it after changing a good cpu though still display   not ok)   6. CPU internal  display section Damage- Sometimes  phone all section is working ok (without  display) but have no display  still afterchange a good display (soft ok also) now you need to change must be cpu.   because many time i seephone all section work ok but have no display, after changing a good   display phone is ok100%. can anyone question, though its problem from cpu so how phone all   section work ok. ans is- phone all section work ok because only display area damage internally   in cpu but all othersection have no problem.</blockquote>
