Hi Richard, 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 number of the TV.
What other devices are connected to the TV using what kind of cables please?
However, it would appear that this is a duplicate question as there is an earlier question and another site member has responded.
Please click HERE.
I would now opt out.
Apologies for any inconvenience.
