Other Issues
Use these procedures to resolve other issues that may occur.
Problems Possible Solutions
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.
After extended use, you may feel heat when touching it. This heat is not a
defect and does not affect the TV's functionality.
The TV smells of plastic.
This smell is normal and will dissipate over time.
The plastic cabinet makes a
"clicking" type of sound.
The "clicking" sound can be caused when the temperature of the TV
changes. This change causes the TV cabinet to expand or contract, which
makes the sound. This is normal and the TV is OK.
When I turn on my TV, there
is a delay for a few seconds
before the picture appears.
Is this normal?
Yes, this is normal. The TV is initializing and searching for the previous
setting information.
