Repeated issue with Freeview disappearing overnight

I purchased a new 50" LG television a couple of weeks ago from Curry's but am having a repeated issue on the Freeview channels. The issue is that despite several attempts at clearing the memory and doing an automatic retune on digital channels - after an overnight switch off, they have all gone again by morning. 

 

I can view everything as normal during the daytime - including if the television has been turned off for a number of hours. The issue arises when I turn on the TV the following day after it has been turned off overnight. I am continuously left with just five channels starting at number 301 as per the image below.

 

 

I have a set top box from BT and have tried retuning the TV both with the box connected, and without. The results are the same each time, no matter what I try. Daytime all is well, but after an overnight period I am left with the screen above.

 

 

As you can see from the image below, everything is as it should be after yet another retuning session this morning. 

 

 

 

My previous TV was a JVC Fire and used to stop receiving the Freeview signal just after 1am each morning. I did a bit of googling and found out it was an energy saving thing to ensure the TV isn't left on all night if you fall asleep in front of it. With the Fire TV was there was a way to override this in the settings, although I never did anything about it as 99% of the time I was already in bed and therefore not a problem. I'm wondering therefore if this issue on my LG unit is in some kind of similar vein and just needs something to tell it to stop doing this reset??? 

 

Can anyone help me please as I'm getting sick of doing an auto tune every morning. 

 

Many thanks in advance.
