Possible Solution
• Is the power cord plugged in?
• The lamp cover is ajar. Firmly replace the cover.
• Press unit POWER button down over 7 seconds. The POWER
indicator goes out. If the Power was On, the screen will also
disappear. After 5 seconds, turn Power On and operate unit normally.
If the steps above do not restore normal operation, disconnect then
reconnect the AC plug and turn the power On.
• Please replace lamp with a new one. Please consult your nearest
dealer, if problem persists.
• Check whether or not the vents are clogged.
• Is the set being used in a location that is hot?
• Please consult your nearest dealer.
• Are the batteries dead or inserted incorrectly?
• Is the Remote Control sensor in direct fluorescent lamp light or other
strong sources of light?
• Did you correctly set the Remote Control code?
• Is the antenna or antenna cable old, broken, or shorted out?
• Is the antenna cable connected properly?
• A sudden temperature change may have caused condensation in the
internal optics which results in blurring or vertical lines. Please wait
until room temperature is normal and constant before turning power
ON. These symptoms will clear up as time passes.
• Depending on the connected device, a 1080i input signal may cause
the picture to flicker. If the connected device has a format selection
switch, set the format to 720p.
• When using a VCR and selecting channels on the TV, is the
TV/VIDEO mode for the VCR set to TV?
• Is the antenna facing the right direction?
• Is the antenna receiving any signals reflected off of mountains or
buildings?
• When using 16:9 image software (cinema vision size software, etc.),
there is no picture at the top and bottom of the screen.
• Please adjust the V-Size. This is not a malfunction.
• This is the sound of the internal Starting UP. This is not a malfunction.
• This is a characteristic of the LCD panel and not a malfunction.
• This is because the cooling fan is operating. The fan will stop after
about 1 minute.
