The BNZ110 is designed to be for Zenith by default. If it gets changed and won't work, then take the following steps.
1. Remove the batteries.
2. Hold the power button down for 10 seconds.
3. Reinstall the batteries.

This works for many Zenith TV's.

Here are the codes for Zenith if that does not work.

713 502 606 409 710 701 507 714 405 712 015 916 008 002 115 224 324 126 326 826 228 430 632 435 437 903 407 505

Some more suggestions to see if your remote control has just lost it's programming is try unplugging your television and taking the batteries out of the remote control for atleast 5 minutes. If this doesn't work, or you've tried tvtek's advice up top and you still can't get your remote control to work, I would try ordering a original replacement remote control for your specific television. I would not recommend purchasing a universal remote, because half the time the problem with it not working could just be caused by it using the incorrect code. If you go to a site like http://www.remotecontrolscenter.com and look through their site for the exact model number of your television and purchase that remote control than you'll have a good idea if it's the remote or the television. Most likely you'll find it was the remote control!
