How to turn off the picture but not the sound on my samsung tv "50mu630d" I only want to listen to music
Some tv sets from the old days used to have a sound only option - these were almost exclusively dedicated to local cable networks such as Rediffusion.
To the best of my knowledge, today no such sets offer that facility as even the audio only digital channels want their audience to see the logo and be able to access the programme schedules and other information.
If you want to kill the picture temporarily while you listen to music you will need to access the menu and turn the brightness to minimum.

I am trying to repair a Samsung 60” LED tv, model UN60H6203AF. There is no picture and the LED lights work when unplugging the power to the main board. I replaced the main board and as soon as I turned on the power a module fried and burned up. I also have a new T Con board coming in the mail as the current one does not have the 3 blue LED lights lighting up, which I have seen on YouTube videos.
Does anyone know what the issue could be that caused the new main board to burn up as soon as I turned the tv on and what exactly got fried on it and what it’s purpose is? I have attached a photo of the burned main board, right below the mounting screw. Could it be a bad power supply?
normally, I don't entertain television fixing questions, because it is impossible to diagnose online. However, I will toss a few things in.
The main board might be faulty, or out of a scrapped set.
Check the back of that board in-situ and see if anything near that IC chip is contacting the television fixing frame.
More likely a voltage regulation on that board, rather than a faulty power supply. You can check output voltages, but only if you know what they are supposed to be?
Unfortunately it is a minefield, posters change every board and don't have a working set. You need all the test equipment and the knowledge of boards at component level and what everything does.
