Many reasons could result in your remote not working with your unit, some of them are:
• Batteries are not working and not installed correctly
• Try rolling the batteries inside the battery compartment.
This sometimes works as the springs are not making a good connection to the batteries.
• Remote may not be compatible with your equipment.
Most likely if you purchased it from us, it is compatible.
• Make sure your remote does not need programming. It shouldn't unless we specified that it was a universal remote.
• Remote needs to be paired with your TV. Please refer to your TV's operating manual for instructions.
• Your Unit's Infra-red receiving diode has gone bad. This is usually the case with older TVs and VCRs.
• Your remote is broke. This could be possible if the shipping company was not careful enough when shipping it. We always test the remotes and make sure they are working before they leave our facility • Please also refer to our "Product Description" area on our product detail page for the remote to see if there are any special instructions.
