Autosleeper TV

There is a small on/off rocker switch on the bottom (lower edge) which needs to be on I think if it is on it has a blue LED 

Our TV is also new but that is how I remember it. 

If you haven’t sorted this and as you say ‘There seems to be no power’ it may be worth phoning the place you bought the Autosleeper & TV from or post the question on the Autosleeper Forum.  Good luck.

We took van and tv back to dealer who showed us that at the end of the power cable where you plug the tv into the van socket, you can unscrew and that's where the fuse is and it had blown. Hope this is helpful for anyone else. 

I also looked up and registered in the auto sleeper forum - which until jayoutdoors mentioned didn't know existed. Thank you jayoutdoors. It is a very helpful, friendly and useful site.
