NS-28D310NA15 Insignia 28" LED TV Problem Solution Good picture, but no sound. • Increase the volume. • Make sure that the sound is not muted. • Make sure that you do not have headphones connected. When headphones are connected, no sound comes from the TV speakers. • Change to a different audio mode. • If you are using a home theater system, sound bar, or external speaker system, make sure it is turned on and is not muted. • If you are using a home theater system, sound bar, or external speaker system and have connected it with a digital optical cable, set the Digital Audio/SPDIF option on the AUDIO menu to PCM. See the Digital Audio/SPDIF option in "Adjust sound settings" on page 55. Make sure that the audio cables are connected correctly and securely to your TV. • Make sure that the antenna or cable TV is connected correctly and securely. See "Connect a cable or satellite box" on page 14 or "Connect an antenna or cable TV (no box)" on page 19. • If you are using an antenna, the digital channel signal may be low. To check the digital channel signal strength, see "Check the digital signal strength" on page 60. • The audio cables you are using may be bad. Try a new set. Poor picture. • Make sure that the room is not too bright. Light reflecting off the screen can make the picture difficult to see. • If an S-VHS camera or a camcorder is connected while another connected device is turned on, the picture may be poor. Turn off one or more devices. Good sound, but poor color. • Adjust the contrast, color, and brightness settings. See "Adjust the TV picture" on page 52. Problem Audio noise. No output from one of the speakers. After images appear. Solution • Other devices (for example, a surround sound receiver, external speakers, fans, or hair dryers) may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference. After you have determined which device is causing interference, move it further from the TV to eliminate the interference. • Adjust the audio balance. See "Adjust sound settings" on page 55. • Make sure that the audio cables are connected correctly and securely to your TV. • Do not display a still image, such as a logo, game, or computer image, for an extended period of time. This can cause a permanent after-image to be burned into the screen. This type of damage is not covered by your warranty. Remote control Problem Remote control does not work. Solution • Make sure that the AC power adapter is correctly connected to your TV and a power outlet. • Make sure that there are no obstructions between the remote control and the remote control sensor on the front of the TV. • Point the remote control directly at the remote control sensor on your TV. For the location of the remote control sensor, see "Front" on page 9. • The supplied batteries are wrapped tightly in clear plastic. Make sure that you have removed this plastic from the batteries. • Make sure that the batteries are installed correctly.
