Hi and welcome to justanswerPerhaps I can help you with this problem but first i would have a few questions;
Is this tv connected to a cable box/converter,satellite receiver,digital converter etc ?
Do you have other equipment like a dvd,bluray,games etc. connected to this tv ?
If so, do they have the same problem ?
Digital cable box. DVD has volume.
O.k then it sounds like your cable box may need to be rebooted.To do this,pull the cable box`s power cord off the wall outlet (cable box only) for a couple of minutes.In the mean time turn off the tv and turn it back on only after you plug back the cable box power cord.I will be in standby, let me know how it goes
YOU ROCK!!! Saved me from buying a new TV. TY,TY!
My question was answered and the problem fixed
