Hi @Astrofannumberone  Alternatives are  INFO -MENU - MUTE - POWER  and MUTE - 119-Power.   However if to no avail  unplug at the mains off the TV for at least  5 minutes and see if  this makes any difference.  You could try a flash reset which does not require the TV Menu. Under the Samsung logo on the TV you have a small black button about 2-3cm in from the bottom edge. With the tv turned on
1. press the button at the logo for 5-10 seconds
2. Release the button
3. press the power  button on the TV Remote for 5-10 seconds. Tv goes black and then restarts after a while. This is  called the flash reset 

However some inadvertent changes in the Secret Menu can result in critical errors.
