Scrible strip broken: solved

[rolfdc]

Can someone help me to troublehoot the issue?

This is 'vegas mode



Thanks for any tips.
I am not afraid to open the console.

Can you post the Snap here? It might be hardware or it might be a setting.

Doesn't look like a setting issue. There isn't anything to cause a white out of half a bank's scribble strips. You can adjust contrast and brightness across all strips but you can't do anything to make a whole panel go white.
I might suggest doing a console initialization, but I have low confidence that would resolve the issue.
Under Setup flip the console to Wing Data for the data partition and backup everything to a computer via USB before initializing.

A little update about my investigations:
I found a video on how to disassemble the wing, en reach the pcb's with the faders and scrible strips:

Here, I learned that I need to be extremely careful with cable connections, I plan to check if I can leave everything connected as much as possible.

As far as I can see the issue is indeed a hardware issue, the LCD fluid seems to be gone.

My plans are to open the Wing, and check if I can exchange the LCD with the 'unused' one from the right upper side of the console.

I wonder if there is a way to order spare parts for the Wing. Is there anybody out there with experience?

From the earlier post where you show the vegas mode "all white" scribble, it really looks like a LCD HW driver issue, or if you're lucky a cable that moved somehow if it's the LCD HW. Fixing it is certainly possible, and finding the exact same LCD assy/part may be difficult. We'll help if we can...

It happens that the display shows something, and when I apply gentle pressure on the LCD, it sometimes changes the pattern



I think that a bad connection could be the issue, and my hope is that nothing is really broken

New update: I opened the Wing, without disconnecting any cables, that looks like this:



From there, I could remove the pcb:





And then I swapped the 2 lcd units that are on the board.
Then I tested the Wing, and the failure also swapped.
So: the LCD unit is broken.
For the time being, I used the lcd from the upper right side ( thanks Behringer for the spare)

I found the replacement spare part also in Switserland:

Conclusion: as soon as I receive the part, the issue will be resolved.

Do the Scribble strips just unplug? No soldering required?

[rolfdc]

The lcd's are connected with ribbon cables plugged in to the board, no soldering required.

Here is the 'fixed' Wing


Only one little screw left
