GPS Repairs - VW Passat B8 (3G) - display error / touch error MIB 2.5 Discover Pro display

Display Issues / Touchscreen Issues on the 9.2-inch Discover Pro Display - MIB 2.5.

Two vertical stripes or lines are visible on the display; the stripes are particularly noticeable against a light background or when viewing the display from the side.
In some cases, the thin line moves along with the touch when operating the touchscreen.
Only stripes are visible on the display; the information on the screen is no longer legible.
The touchscreen responds to touch only in a limited area; individual letters are not accepted during input, or the touchscreen is completely unresponsive. “Phantom inputs,” also known as “ghost touch,” occur, causing the screen to move on its own. The navigation device’s touch function operates independently; for example, the device automatically dials saved contacts from the phone book or changes radio stations.
Bubbles form under the glass of the Discover Pro.
The display fails partially or completely and can no longer be operated.
