Screen shows only a blue line

I have changed the display on a phone, but after a few days (it worked fine initially) it changed into a single blue line showing on the screen.

I think this is the new screens interpretation of the Apple symbol, since it changes into another blue line after about 10sec.
I have tried opening it again and reconnecting all the connectors from the display to the logic board, but to no help.
Anyone have any idea what can cause this?
Thanks a lot,
