Thanks for the Question
I will need the model number of the TV please found on the back of the set?
It must be there im in the wilderness without it....
Yes that may be the case if its wall mounted and you dont have the user manual with the set, you see if I had the model number I will be directing you to factory reset the TV in the settings menu now I dont know if you can do that yourself but their will be a settings menu the factory or shipping reset will be in there
Yes but you need to get into the settings menu so you can reset the tv to factory default obv without the model number I cant tell you exactly how to do that
Yes its likely the box was faulty in that case
I was under the impression you was viewing through an aerial but if you was using the box and losing channels then its the box that controls all that the TV is just a moniter for the box
So its very likely now that you wont have a problem so dont bother with the factory default
yes see what happens but as I say the box IS the tuner all the channels and tuning are done with the box the TV does none of that
only when you use an aerial
Let me know if I can do anything else
Please remember to rate the answer positively thank you
