Sound will not adjust by remote or on tv itself

That is the small board in the TV that has the inferred sensor located on the board, it may be a little hard to find though, but if you can find one it won't be expensive, most the times when sets are scrapped out that board goes in the garbage because it has a really small failure rate.

I am not certain what you mean by remote is OK but the way remotes work with TV sets and cable boxes is that the remote sends channel info to the cable box and sound control to the TV set. Is the sound on full blast? Some cable boxes allow you to adjust the sound too. Without more information it is difficult to know where you are having a problem.

Hi,

It sound like the remote is powering off the cable box but not the TV. The remote control may need to be reprogrammed to the TV. When you press power it may only power off the Cable box. At that point, try pressing the TV button on your remote and then Power. If it does not power off the tV after pressing the tV button, the remote may need to be reprogrammed to the tv. Cable companies usually have the codes needed to program their remotes to the TVs.

Remote Control volume UP could be sticking inside the remote itself. Remove batteries and manually turn TV on and see if sound works ok.

After only three days I would take it back, or at least take the remote back and try it on a different sound bar.

The remote control need cleaning. If you wish to know more about how to clean and repair a remote control, check this link. Pull up older posts there. One among have details.

tried to hooked up with an air antenna. if you can not get any channel and just a white raster or snow, it could be the tuner get fried.

Go into ur tv menu again,go to sound option again check what on the writing highlight on the tv SOUND SETTING now is it said VARIABLE SETTING.Than it is the sound setting problems,go into that highlight word VARIABLE SETTING just press the enter button on the remote to change it back to FIX SETTING.This should and will solved ur tv sound setting problems.If the sound setting already highlight word is said FIX SETTING.Than the tv have bad incomming broadcasting input signal cable or ur tv have bad or dead speakers problems to the tv itself.Not Sound Setting problems.

Check on the manual control on the tv itself Vol + - buttons see if functions normallyTry website like Remotes.com to buy a remote same as an exact original remote.

your remote should be opened and service it, a +button -button are not toggling making contacts, or one is holding permanently inside a remote thanks.
