You can resolve this problem by factory resetting the TV.

1. press the UP Arrow Button on the Remote of the TV.
2. While Holding the UP Arrow Button on the Remote, press the POWER Button on the TV.
3. The TV will turn ON and turn OFF automatically.
4. Please skip the Auto programming, if you are using a Cable Box or Satellite Box.
5. After that, perform the initial setup.

(Note: Resetting will reset all the Settings including the Network Settings (if any), to its factory defaults)

NOW, the issue is RESOLVED!!!!!
