Hi kohay
Below are some steps that you can try in doing digital tuning:
1. Press the [HOME] button of your remote controller.
2. Go to the Settings menu, located at the bottom of the Home screen.
3. Select Channel Setup → Digital Setup → Digital Tuning → Digital Auto Tuning.
4. When asked "Do you want to start Auto Tuning?", select Yes
5. Make your selection between Antenna or Cable
6. When selecting Antenna the auto tuning for Antenna starts at this point
7. If Cable was selected in the previous step, the menu for Cable tuning will now appear.
8. You may choose to set Scan Type, Frequency or Network ID manually according to specific network parameters, received from your broadcast provider
If you have not received anything, we recommend to use the default setting:
Scan type: Quick scan
Frequency: Auto
Network ID: Auto
Operator: Select the name of your broadcast provider from the list
If the scan does not find any or all channels, you may try to change the Scan Type setting to Full scan.
IMPORTANT: It may take an hour, or longer, when selecting Full scan to tune your TV.
NOTE: If you have problems with the Cable tuning procedure, please check with your provider as they may use different settings.
9. Proceed by selecting Start.
The TV will now start tuning. A confirmation message will appear once completed.
Hope the above steps help.
Thanks!
Regards
Ann
