Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?



Hi

Half a year ago my girlfriend accidentally gave my Z3 Compact a rollercoaster ride in our washing machine (full tour). The screen broke, but it could turn on and everything looked fine (gave no errors) when connecting to HDMI.

Yesterday I received a replacement LCD, which gave it a new life. It seems that everything works except for the rear camera. When opening any camera-app, the HUD is visible, but image is black, and no error. If i switch to front camera, which works, and back to the rear camera, it shows a freezed image of the last image from the front camera.

I checked some debug-apps to see if it detects the camera-module, and it does. If it's connected, alle the specs of the camera is listed, and if disconnected, the module is not listed.

I then got a broken Z3 Compact from a friend, and I tested both rear camera modules in both phones. The modules are working in his phone, both doing the same black screen in mine.

I tried hard reset, PC Companion-repair, updates, clearing camera cache etc., but with no luck.

Do you have any suggestion to how I can fix this?
Do you know where on the motherboard I could look for dirt in relation to some "rear camera bus/chip"?

Thank you for any help!
