service provider.

•  Verify that the set-top is set to the proper screen type and resolution.

•  Verify that the current TV program is broadcast in color. 

•  Adjust the TV color controls.

•  If you are using a component video connection (YPbPr), check that all connectors are completely plugged into 

the set-top and TV.

A message appears on the TV screen when the set-top and the M-Card module are receiving software updates. 
In addition, download information also appears on the front panel of the set-top during these updates. Wait for the 
current time to display on the front panel before continuing. When the time appears, the update is complete.
