I have a Samsung tv, it's our secondary tv, and we are unable to change the channel. This happened after the power outages. I have unplugged and restarted the cable box, and it still doesn't work. Do you have any suggestions or what I may be able to do to fix this?
Does the tv change channels using the tv remote? Will the tv change channels using the + or - found on the tv? You would test this by being on "antenna"
Does this tv need to be set to channel 3 (if on coaxial cable from cable-box)? Is the tv set to the correct source for cable input?
