Have TV Questions? Ask a TV Technician
What exactly is the volume issue you're having- please elaborate?
sir , you have 3 open request
If you need help please respond here
What is connected to this tv ?Cable box,satellite,dvd,games etc. ?
same problem on all devices ?
When you say cable , is there a converter as well ?
Do you have a cable company remote ?
So the tv is connected directly to cable and no cable box/converter with its own remote
The only remote used to change channels is the tv`s own remote , is that correct ?
Sorry but your last statement is confusing
Yes those sharp do have problems and its audio circuit is one of them .
Reason for asking about a cable box is that its audio out could be used for a sound bar for example ,which would be cheaper than a $250 repair on the tv
The TV's optical audio out should be fine though and could also be used .
check what ?
The optical out ?
You can`t really tell if there is sound but with an optical cable and plug it into the tv then at the other end if you see a red light then it is active.
Pleasure talking to you and please do not forget to rate ( with the stars ) so i can get compensated for my time helping you.
