Still Horizontal Lines Across the Screen

[do1984]

Hello.

I have a 15" rmbp mid 2012, and some time ago several lines appeared across my screen. They don't flicker or move, when I scroll or drag some window, the lines remain still. I've already disassembled my rmbp, disconencted and then reconnected the cable but the lines persist. It's not a driver / os version issue because I've tried multiple OSX versions (10.9, 10.10 and now 10.11), and Windows 10 via bootcamp.
Have any of you had similar issue? I suspect the panel is faulty. Could it be my discrete gpu? (Geforce 650M).
Any tips? (besides taking it to an Apple Store)

Take it to the apple store.

No offence but I wouldn't of disassemble the macbook in the first place and just taken it to the Apple store. Now, you may be out of luck in getting it repaired for cheap or replaced.
