Hi, I am using a QE55LS03RAUXXU TV with one connect and invisible
cable. The TV started to switch off on its own for 2 days. And not doesn't
switch on but does have the standby light on. I have checked there is
power running through the power cable to one connect and invisible
cable. Does this mean that my one connect box is faulty?

Hi @Naz7866  Firstly  unplug  disconnect tv and connections from the mains  for about a minute before reconnecting to see if that solves the issue.  If not  whilst there does not appear to be an issue with cabling I would suggest you disconnect the  cable from the One Connect Box  before reinserting to see if that makes a difference and if the screen menu is displayed. if still problems there may be an issue with the One Connect Box  but would to connect Samsung Support for advice. 

some further information in this article https://www.samsung.com/uk/support/tv-audio-video/my-tv-wont-turn-on/ 

I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.

Thanks, I have tried all the troubleshooting but no fix. I just need to figure out if it's the cable or the one connect box. I spoke to samsung and they said same thing, so will have to buy a cable to check if that resolves it. Its only £104 for the cable lol. Hopefully I can return it if it isn't the cable.
