I do not want to switch to a phone call and pay another 26 dollars for a tv that I just purchased a week ago. This should be under warranty. If you can help me, then please do so. It may be the cable converter box and not the tv. I was hopeing you would have had this problem before and could give me an anwser
TV Technician: Jack, Technician replied 7 months ago

If you received a $26 phone offer or any offers they are automated by the website ,NOT BY ME , I`m an independent tech. and have no control over those

If you got this tv only a week ago then return it for an exchange or refund , not a repair

It has a main board problem

Customer reply replied 7 months ago
Thank you
TV Technician: Jack, Technician replied 7 months ago

If you turn the tv off and it clears the problem temporarily then its not a cable box problem
