Answer for MXQ box keeps shutting down my TV during movie play…why?

Hello all
I was here to find a solution for the different issue with my box. But reading the thread I will answer your question. 
I have been using box from last 5 months even I was surprised when the blank screen was occurring randomly I was I was little worried that is my box bad or is it spoiling my television.
Then one day I realised that screen goes black and comes back in few microseconds the reason was when you’re somebody in another room in my house used to turn on return of any other electrical devices I was getting that blank screen
So don’t worry it’s not about your box it’s not about your television it’s only about electrical connections and it doesn’t do any harm to any of your instrument
