The above link goes to lg's website describing the red flashing light where the power switch is, and
another switch down below which can turn that light off.
Try switching that other switch below off so the light turns off. Then, switch it back on.
If that doesn't work, then service should be scheduled for this discontinued model.
Hope this helps on your lg tv.
