Can you give me the model number?
The model number should be on the back of the set. To give you exact detail
on auto scan , I would need the model number. The model number should also be on your instruction manual.
Auto scan is a function that checks all available channels and adds them to
a list of channels in your tv.
You would go to the menu and find cable/ antenna setup and select which one you are using. After making the correct selection. You should see a menu function for channel
auto scan. You would select auto scan and the set will go into auto channel set.
This could take a few minutes. Once it is completed the auto scan required message
should go away.
