I don't believe a bad LIDAR cable would be responsible for a "no image" condition like you're experiencing. I would double check your connections and make sure they're secure. Inspect the connectors for foreign objects and debris and make sure they're not damaged. Depending on where you got the replacement part from, it's a possibility you may have received a defective part. If your old screen still works, you could reconnect that to your device to narrow out the possibility of a defective part.
