The Vizio VO47LFHDTV10A is a 47 inch flat screen television. It has a built-in digital television tuner. Some of the accessories that come with the television are an HDMI cable, a cleaning cloth, and a remote control. The remote should work fine out of the box, but there are issues you may encounter such as dead batteries or a blocked sensor.
Video of the Day
The sensor is on the front of the set located near the bottom. The sensor in the TV and the signal in the remote have a distance limit. You must be within 30 feet of the sensor on the TV and you need to be pointing at an angle of no more than 30 degrees to the left or right of the sensor and no more than 20 degrees above or below the sensor for the set to receive the remote's signal. Also, make sure that nothing is blocking the signal from the remote to the TV. The signal will not transmit through furniture, people, or other objects.
The remote control uses AA batteries. Make sure the batteries are still good. If you are not sure, replace them with new batteries. Match up the batteries to the plus and minus symbols in the remote when you insert new batteries.
Signal and Settings
If you have a VIZIO universal remote be sure to press the "TV" selection button to make sure the remote knows you want to control the television. Remove the batteries, press each button once, place the batteries back in and then try the remote. This may reset your remote and cause it to work correctly. Check the remote for a signal. There is a small bulb at the end of the remote that lights up when you press a button if the remote is functioning properly.
