Hi @lauracolf

What is the signal source for the TV e.g. TV antenna (RF coax cable connection), cable box (HDMI or component video/audio connection (RGB video + RW audio cables) etc?

Is the sound heard from the TV speakers or a sound system connected to the TV (digital audio out cable or HDMI)?

Is the sound OK when listening via headphones connected to the TV's headphones jack on the back of the TV?
