Symptom
After starting an Activity with your Harmony 700 remote, everything turns on correctly, but no picture comes up on the TV screen.

Solution
The Television may be out of synchronization with your remote or may be configured incorrectly.

1. In front of your Television, press the Help button on your Harmony 700

   

2. Answer No when asked "Did that fix the problem?"
   

   

   
   
3. The Harmony 700 will then ask, one by one, if all of your required devices powered on when the Activity was started. Answer Yes or No until all required devices are powered on
   

   

   
   
4. Answer No if the remote asks if the TV is set to the correct input needed for the Activity. In this example Input 2 is used, though this may vary from your setup. If the TV switches to another input but no picture is seen, continue answering No until an image appears
   

   

   
   
   
5. If you now have a picture on your TV screen, answer Yes when asked if the problem is now fixed. Your television was simply out of synchronization with your Harmony 700 and should now work correctly. Please try switching between your other Activities to see if they switch correctly. If this has not fixed the problem, proceed to the next section Confirming your Activity Settings

3. Click on the   button for the Activity you wish to troubleshoot
4. Select Review the settings for this Activity and click on the button
   

   

5. Confirm the input chosen for your television is correct. Select No, I want to run the setup wizard again to change these settings and click on the button
   

   

   
   
   
6. Click on the Next button through the Activity setup screens until you arrive at the screen asking the question "What input or channel does your ... TV need to be on? From the list, select the input that the TV uses for this Activity. Once finished, click on the button
