Hi, well i have a samsung smart tv wich was with a problem for some reason it was switch on and off for no reason it was like this for amost 3 years without any explanation and i was so close to spend mouney on other tv becouse it was so anoyng I couldn't watch anything for long time withou it go on and off so I just come to let you guys know that if you have a smart tv or any TV like my before you spend money in a new tv just do this - open de back cover tv disconnected every single plags and use a small vacuum cleaner with a brush tip to suck up all the dust because Samsung TVs don't like dust accumulated inside. Thank you very much a very good day for all of you!
