Facing TV Problems? Ask a TV Technician.
Hi Carolyn , I`m Jack Perhaps I can help you with this problem but first a few questions ;
Is this tv connected to a cable box/converter,satellite receiver that has its own remote or are you using the tv`s own remote to change channels normally ?
If you do have a cable box or satellite receiver and used the tv`s remote to change channels then go back to that one channel you said you had and then put the tv`s remote aside and use the cable box remote to change channels .
Give it a try and let me know
