Mag 254 stop playing on my samsung TV

[tziminhio]

Hi to everyone guys. I use mag 254, 3 months now and many times it is disconnected and displays the message:
"No signal
1) Check the connecions of cables and the settings of the device
2) Press the SOURCE button to select the port "

Of course everything is ok with the connections etc. Sometimes when I select another HDMI port it plays but not always. Today I tried all HDMI ports but it doesn't play. The strange thing is that it plays with my pc monitor and I don't know why. My TV is new ( model samsung 40j6200). I have tried all video settings of MAG 254 (connecting my PC monitor) and it doesn't play on my TV. Tomorrow it may will play. Maybe is a setting from TV? But what? I have tried everything, all the sollutions with menu button etc but the problem still remains.
Thank in advance guys.

It has only one blue light and it's ok. Eventually, the stb connected with my tv (I changed the resolution) but during I was watching tv it was disconnected 2 times and now it's ok. Maybe tomorrow, can't connect with the tv again. Sometimes tv and stb can be connected and sometimes not. I can't find a solution to this problem. This happens from the beginning I bought the stb.

I have a newer LG Smart Tv and a Panasonic Smart Tv but I would NEVER allow either of them to connect to the internet or access anything that it connect to them. Smart Tv's report on what you connect, what you watch, the time you watch it and basically spy on what your interests might be. If you're smart, turn off and block them from connecting to the internet and you might find your connected hardware is no longer having issues. Smart Tv's want you to use whatever services they want you to use and create issues if you don't. Remember all those agreements you agreed to ? If you don't read them, you won't know just how bad it can get.
