This is a repair service for the center information screen in your Mercedes-Benz W203 C Class or W210 G Class instrument cluster. If any onboard modifications are needed to adjust contrast and brightness, then they will be completed during the repair.
These screens fade and distort over time. It is a common repair for these models to replace the screen. We do sell the screens separately if you want to DIY. Sometimes these clusters need chip modifications to adjust the brightness level. This syncs the power output of the cluster to the LCD screen and ensures they are within specification.
