How to Troubleshoot a Comcast DVR
Comcast offers its customers the chance to add DVR service to their cable package. With a Comcast DVR, you can pause and rewind live TV, record your favorite programs or set a season pass to record all episodes of a particular show. An example of a Comcast DVR set top box you can use is the Motorola DCT 6412. If you have a problem with the Comcast DVR, try these techniques before calling for service.
Unplug the Comcast DVR and wait a minute. Plug the unit back into a working wall outlet. This will force the Comcast DVR to reboot. This can resolve frozen screen and blank screen issues that may occur.
Check that the outputs are installed correctly. If you can’t hear or see Comcast programming, the DVR may not be hooked up correctly. Make sure the audio and video outputs are hooked into the corresponding TV inputs. You may need to adjust the output format if you are using a high definition TV. To do this, press the “Menu” key on the front of the set top box. Scroll through the options until you find the “Output” selection. Press the right scroll key to view the different formats until a picture displays on the screen. The coaxial cable also will need to be installed for operation.
Change the channel using the Comcast DVR remote. If you view a black screen, you may be tuned to an unauthorized channel. Also, select “Cable” on your remote control to view your Comcast channels.
Adjust your recording options. If you have a problem using the digital video recording features, view the options by hitting the “DVR” button on your remote control. Highlight a show to review the recording options to make sure that they are correct.
