Check for tangled, twisted, or misaligned slats
Straighten bent slats by hand or replace damaged ones
Reattach any loose slats to the headrail or carrier clips

Replace broken lift cords or restring the blinds
Test the tilt mechanism and replace a damaged wand or tilt rod
Clean dust and debris from the headrail, cords, and slats
Tighten loose brackets and mounting hardware
Replace broken end caps, cord locks, or tilt gears
Reset the blinds by fully lowering and raising them
Replace damaged valances or bottom rails if needed
Use a repair kit for broken clips, ladders, or cord mechanisms
