Verify that the TV is powered on and set to the appropriate 
input source for the cable terminal. 

Verify that the cable terminal is powered on and tuned to an 
authorized cable channel. 

Verify that all video cables between the cable terminal and 
the TV are firmly connected. 

Verify that the coaxial cable feed is firmly connected to the 
cable terminal and the wall jack. 

If the cable terminal is connected to a home theater unit, verify 
that the home theater unit is powered on and set to the 
appropriate input source. 

Press the • key to cycle through the available output 
formats until a picture displays on the TV. 

Verify on the User Settings menu that closed captions are 
enabled on the cable terminal. 

Verify that closed captions are enabled on the TV. 

Some SD programs are broadcast in the letterbox format with 
black bars above and below the picture. Some widescreens 
TVs offer a zoom feature that may be able to remove the 
black bars. Note: If tuned to HD and the TV Type = 4:3 
LETTERBOX, black bars will appear above and below the 
picture. Try setting the TV Type to 4:3 PAN/SCAN to get a 
full-screen picture with no black bars. 

A broadcaster may include black bars on either side of a wide 
screen broadcast.  This is called a “hybrid” aspect ratio and 
results in a black border surrounding the video on a 4:3 TV. 
Because this is part of the broadcast, the cable terminal 
cannot correct the video. Borders can be eliminated by 
selecting the 4:3 PAN/SCAN option on the TV Type setting.  

The DCT3080 includes an integrated hard drive and a fan for 
cooling. During normal operation, the DCT3080 emits a low 
humming noise, similar to a personal computer. The noise 
varies in volume occasionally when the speed of the internal 
fan adjusts to changes in the temperature around the 
DCT3080. Please note the hard drive will stay on even when 
the DCT3080 is turned off.
