BMPCC4K Purple/pink screen issue

PostFri Dec 15, 2023 7:35 pm

Hi everyone! I am writing this post accordingly about the problem that I had with the screen of my bmpcc4k.
When I turn on camera screen goes with purple/pink and blue lines (photo attached). But when it works for half an hour, then the screen works normally (when the camera warms up). Something similar is described in this post (viewtopic.php?p=229544#p229544). Where KevinBurke32 mentioned LVDS cable.
I quote his words: (I had an engineer at work take it apart to see if he could find the source of the problem and he discovered it immediately. The wide, thin LVDS cable that runs the monitor had been pinched in between other internal camera components when the camera was manufactured (total manufacturing error) and over time the friction caused the cable to become damaged).
I was searching for that cable but I have no idea what it looks like since I haven’t taken the camera apart.
But i found some cables that maybe could be correct ones:
Spare ribbon cable and spare LCD jumper cable (screenshots attached)
Maybe someone can tell me where to dig, which cable should to buy to fix that issue.
I'd appreciate any hints.

I think I would send it to BMD for repairs.

I assume that this is the cable that is shown in the photo and which is most likely not sold separately, and is not separated from the screen and is sold only with it. Correct me if I'm wrong.
