Hi, did you give up on this? I have same monitor and same problem - three lines shows up few days ago :-\
Yes I did.
I tried a couple of things though.
* Cold spray on all the ICs
* Wiggleing all the connectors
* Disconnect och connect all connectors
* Took apart the panel itself
The error did not change because of this. It changed only with time so nowadays the whole display is filled with these lines.
To sum it up:
I bought a new monitor - this time not an EIZO.
