Check all wire connections.
Unplug the TV for 30 seconds, then try operating it again.

Replace the remote control batteries.
Clean the upper edge of the remote control (transmission window).
Check the battery terminals.
Ensure that the signal cable is firmly connected to the PC source.

Compare these values with the data in the Display Modes.
Please check the digital signal strength and input antenna.

Make sure the broadcast you're receiving is High Definition (HD).
HD channels sometimes broadcast Standard Definition (SD) programming, which can
cause black bars.
Set your cable/satellite box to stretch or widescreen mode to eliminate the bars.
Make sure the Component cables are connected to the correct jacks.
If you are using a Cable/Satellite box, you must set Closed Captioning on the box, not
your TV.
Your cable box may need a firmware upgrade. Please contact your Cable company.
This is sometimes caused by compatibility issues with your cable box.
Try connecting Component cables instead.
