My screen flickers after screen replacement?

After i replaced my iPhone 5 display, bought from ebay, my screen is flickering. I´ve used the ifixit pro tool kit, used a ESD wristband and have done the repair exactly as i normally do. I fixed two iPhones at the same time, and both had the problem, but the other iPhone seems to be working as it should now. Any idea on what the problem can be?

Don´t want to sell iPhone screens flickering after a repair.

two scenarios come to mind. defective display assembly or the connector is not seated properly. Start with reseating the LCD connector. If that does not solve your problem i would be contacting the seller and returning or exchanging the display assembly.

In my experience the reason for flickering screens well for iPhone 4 at least is when you unplug the battery while the screen is turned on.

For higher I do not know but make sure you turn off the phone to ensure this does not happen and unplug the battery first prior to plugging or unplugging any screen cables to / from the logic board.

if you do this, unplug the battery without turning it off, can you stop the flickering?!

Yep, sometimes it disappears over time.

I had the same problem after changing the battery. Reconnecting all connectors fixed it. Thanks Lars
