You try your new TV where the working TV is and if it drops you RETURN the TV. Sellers and makers will not fix this one. You have to change the TV out and not keep units that do this.
I won't write at length why you do this. This subject does come up now and then on the web. Get out fast before you are stuck with this set.
My new Samsung smart TV is driving me crazy. Sometimes it gets all of the OTA stations it found, but more often than not it drops half of them. My "not smart" TV did not have this issue. HELP!
