Issues Solutions and Explanations
Your settings are lost after
30 minutes or every time
the TV is turned off. • If TV is in the Store Demo mode, it will reset audio and picture
settings every 30 minutes. Please change from Store Demo
mode to Home Use mode using the Setup procedure. Press the
SOURCE button to select TV mode, go to MENU → System →
Setup → ENTERE.
You have intermittent loss
of audio or video. • Check the cable connections and reconnect them.
• Loss of audio or video can be caused by using overly rigid or thick
cables. Make sure the cables are flexible enough for long term use.
If mounting the TV to the wall, we recommend using cables with 90
degree connectors.
The PIP menu is not
available.
• PIP functionality is only available when you are using a HDMI or
components source.
