hi everyone , im brian, i work in a repair shop. i got the next issue with a Huawei P8. i replaced the entire screen (lcd + digitizer) and after i start up the phone i can see that the screen lights up but doesnt show annything, so bad screen i think. tried another one same results. bought another one but this time full screen assembly with the housing , —> ofcourse same result… annyone knows what the problem is? would be weird that i ordered 3 bad screens (from good companys) anny 1 got ideas ? i would love to hear them. thanks alot!

if you’ve tried 3 different screens then all i can imagine it could be is the circuit board where it connects to (presuming its similar to an iPhone) where the flex cable meets with it’s “teeth”.
