Diagnose your HDMI connection
When your TV has no sound, or intermittent sound drop, and you are listening to something from a device connected with an HDMI cable, one of the simplest potential causes of the issue is that the cable is low quality. Since replacing the cable with a higher quality cable is not always easy or convenient, Samsung Smart TV models have a setting that can be used to adjust how the TV interprets the HDMI signal and improve compatibility with the cable.
Navigate toMenu>Support>Self Diagnosis>Signal Information>Signal History>HDMI Delay Level, and select from one of the options:
(From 2020 model:Menu > Support > Device Care > Self Diagnosis > Signal Information > Signal History > HDMI Delay Level)
- Basic:This is the default setting for normal operation.
- Slow 1:This adds a slight delay before determining that the HDMI cable is not sending a signal.
- Slow 2:This adds a significant delay.
Setting this option toSlow 1orSlow 2will improve the signal quality from a poor HDMI cable, but a side effect is that this delay will also occur when changing the source.
