Check for any physical damage to the camera housing.

3. Check Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the backup camera (refer to the owner's manual).
Remove the fuse using a fuse puller or pliers and inspect it. Replace if blown.
