TRAINING MASTER FOR BLU-RAY (BD)

Does the unit respond to 

buttons on the front of the unit?

NO

YES

If the buttons on the front of the unit do not respond, 

determine if the product has locked up or if the unit will not turn on. 

The problem is not the remote control. Make sure the remote control is 

the remote that goes with that particular model.

Does the remote control 

any component?

NO

YES

Determine which product the remote is not working. 

The customer may need to press the appropriate mode button 

to make the remote operate another component. The remote may 

even need to be programmed to the other component, 

especially if the batteries were just changed.

Have the batteries

been changed?

NO

YES

Ask the customer to change batteries. 

Make sure the batteries are new and fresh. 

The batteries do not need to come from a “spare” battery drawer. 

Do not mix used and new batteries.

Is the remote working at all?

NO

YES

YES

If the remote does not work anything, then walk the customer 

through a remote drain. Remove the batteries from the remote control. 

Then press and hold any button down for a minute. 

This will drain the power out of the remote and reset it. 

Universal remotes will have to be reprogrammed.

Does any remote 

work the unit?

NO

If another remote works the unit, then follow 

the procedure to FOC the customer a new remote.

If two remotes do not work the unit, the unit will need service.

Does the customer want to

program their remote?

NO

Please refer to the OM for instructions on how to 

program remote to TV. Customer wants to program a remote 

other than Zenith or LG, the customer will need to contact 

the manufacturer of the remote control. Codes do not work, 

remote is not compatible.
