Safety first: Remove the battery before inspecting for physical damage.

1. Reseat battery: Remove and firmly reinstall the battery pack. Ensure there is no play.
2. Inspect housing for cracks: Look for signs of impact or flexing near the battery compartment or handle.
3. Test with another battery (if available): If flickering stops with a different battery, replace the original pack.
