I bought two of these but to no avail just put the batteries in and used it and wondered if there was anything else wrong. I did a lot of research online and I hope my solution will help others as well. Directly from the Vizio website I cycled the TV and the remote (I'm not sure which worked, as did both, but considering he got the old remote to work as well I guess I that it turned the remote off and on again). Please try the following before you throw away this nice and inexpensive replacement remote!" Batteries out of the remote. Press each button on the remote when the batteries are low. Press each button at least once. This will use up the remaining charge on the remote and sometimes helps us fix weird issues. Check the remote again to see if it can control the TV now. 2. Turn the TV off and on again. Sometimes the problem isn't with the remote. Sometimes the problem isn't with the remote is the problem with the tv quick way to fix the problem - turn the device off and on again, just unplug the tv and hold the power button on the side of the tv for 15 seconds, this will drain the residual power and confusing issues fixed. Then plug the TV back in and turn it back on en the remote control again to make sure it is a slave otote". helps!
