The problem Try this!
There is an 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 you are mounting the TV to a
wall, we recommend using cables with 90-degree connectors.
There are small particles on
the TV's bezel.
This is part of the product’s design and is not a defect.
The settings are lost after
5 minutes or every time the
TV is turned off.
If Usage Mode is set to Retail Mode, the TV's audio and video settings are automatically
reset every 5 minutes.
Change Usage Mode ( Settings General System Manager Usage Mode) to

humming noise.
Your TV utilizes high-speed switching circuits and high levels of electrical current.
