Other Issues

The TV is hot.
Watching TV for an extended period of time causes the panel to generate heat. The heat 
from the panel is dissipated through internal vents running along the top of the TV. The 
bottom, however, may feel hot to the touch after extended use. Children watching TV need 
constant adult supervision to prevent them from touching the TV. This heat, however, is not 
a defect and does not affect the TV's functionality.
The picture won’t display in 
full screen.
HD channels will have black bars on either side of the screen when displaying upscaled SD 
(4:3) content.
Black bars will appear at the top and bottom of the screen when you watch movies that have 
aspect ratios different from your TV.
Adjust the picture size options on your external device or set the TV to full screen.
