Facing TV Problems? Ask a TV Technician.
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model numbers of the "...Sansui/att överse..."
Additionally, is the TV directly connected to an antenna or cable feed? ...or is a cable box used?
If the latter, please describe how the cable box is connected to the TV using what kind of cable(s).
