Television

No Audio
If all channels are without audio, press the mute button on the remote control or press the volume plus (+) button. If your television has internal/external speakers, make sure the switch is on external. If only one channel is without audio, turn from that channel and then turn back. If that does not work, try unplugging the converter for 30 seconds.

Colored Screens
The television set is on the wrong input. Switch to the cable input using the television set’s remote control.

Black Box In The Middle Of The Screen
This is a closed caption function. Using the TV’s remote control or the buttons on the front of the TV, navigate through the TV’s menu to the closed caption settings. Cycle through ALL closed caption settings until off or disable appears.

Tinted Picture
This may be a problem with the television set. It could also be due to the red, green or blue component cables coming loose on the back of the TV and/or converter box. Check that all cables are pushed in tight.

Channels Won’t Change
Replace batteries in remote control. If the batteries are charged and the remote is working, turn the converter off for 30 seconds, and then on again.

No DVR Service
Turn the DVR off for 30 seconds, and back on again.
