HOW DO I UN MUTE A SAMSUNG SMART TV - Samsung Televison & Video

Samsung Smart TV hidden secret menu allows you to do a factory reset and also connect some Bluetooth devices which you were unable to do before. Be careful while fiddling with these options as I cannot take any guarantee if you spoil the TV settings. The Samsung Smart TV I used in the video is Samsung F4500. The secret menu will not open with a smart remote. You may buy or borrow the original normal rectangular Samsung remote to access the secret menu but I am not so sure that will work.
Here are all methods to access the secret menu of different Samsung smart TV:
Method 1

Put the TV on standby and then push in series these buttons on the remote: 'info, menu, mute, power' the TV will then turn itself on and display a menu.
Method 2

Turn the power off. On the remote, press Mute followed by 1, 8, 2, Power in sequence.
Method 3

With the TV in standby, press the {DISPLAY} {P.STD} {MUTE} {POWER} on the remote.
Method 4

With the TV in standby, press the {SLEEP} {P.STD} {MUTE} {POWER} on the remote.
Method 5

With the TV in standby, press the {DISPLAY} {MENU} {MUTE} {POWER} on the remote.
Method 6

With the TV on standby. On the remote, press Mute followed by 1, 1, 9, Enter in sequence.
Method 7 for Smart TV RU7100, NU7090 Series 7 (suggested by viewer Caleb Harch)

Hi recently I wanted to pair my bluetooth headphones with samsung smart tv and I followed this video.

Maybe it helps you as well.
Goal is to go to the hidden service menu and activate it there.
The key combination is :

Turn off the TV.

1. Info
2. Menu
3. Mute
4. Turn on the TV.

Bad capacitors on the power control circuit board.

Enter the audio setting to your TV. There you can see the un-mute option to TV. Select it; and change the mute function.

Try pressing the mute (speaker symbol with diagnol line) or just press up/down volume button

Try cleaning with a damp soft towel, if this does not work use a micro fibre cloth

sounds like a bad mainboard.
