Introduction
If your Garmin Smartwork 50 LMT has a cracked screen, an unresponsive touchscreen, or display issues such as lines or dark spots, you may need to replace the screen assembly.
The display and touchscreen cannot be separated, so this guide will help you safely remove and install the full assembly.
The steps are simple, but be careful with the internal ribbon cables, as they are thin and can tear easily.
Before you begin the repair, power off the GPS and unplug the charger.
