The TV is tilted to the
side.
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 part of the TV. The bottom portion, 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.
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.
Check the supported resolutions of the TV and adjust the external device's
output resolution accordingly.
You cannot select the
to the TV via HDMI or Component. The external device's caption function must
also be activated.
This smell is normal and will dissipate over time.
Verify that the current channel is a digital channel.
Signal Information
is only available with digital channels.
Remove the base stand from the TV and reassemble it.
