I have seen some cable boxes that have their own volume control...if your sound is low ONLY on that box, then you need to get out your Cable remote, set it to Cable/STB and TRY the volume control on the remote.
If it only operates your TV's Volume, then activate your Cable menu, and see if there is a Audio menu....If so, then LOOK for one of those settings to be the Volume adjust setting. Turn it ALL the way up on the Cable box and leave it there.
Now, as a test, you can check your DVD player's volume level and see if that's loud and the cable box is NOT loud. That would tell you that the box is the culprit, and not the TV set !
But if the DVD player's volume is low, then the TV has a problem with it.
To fix that, I would need you to get the FULL MODEL and the VERSION number off of the Tag that's located on the right side of the Cabinet -- it looks like this --
We have seen that issue on several boxes, mostly the Cable boxes. If the Cable box's volume is set to low, you end up cranking up the TV's volume to compensate and you never get it loud enough to satisfy you ! That's why you crank up the cable box's volume control and leave it there. It won't distort the signal if you do that.
Now, there's ONE MORE THING -- IF you had good volume, and SUDDENLY you have super-Weak volume in certain sections of the TV show (key point here!) THEN you may have activated the SAP/MTS button on your TV's remote control! Look for that button on your TV remote, press it, and you should set it for MAIN AUDIO, NOT SAP AUDIO.
If you have any questions, just ask
If you are finished, please press the ACCEPT button.
Tips are greatly appreciated !
