I just got this Android tv box. Hooked it up worked good, but after about 30 min. Started to freeze up, then lost signal now all hdmi ports say no signal. Called Internet provider was told that there was nothing trying to connect to the Internet. Connected my smart blue ray was told yes your blue ray is connecting. Tried my dad's same Android box same thing no signal and not connecting to Internet with ethernet cord not wireless. Both boxes work fine on my parents tv.
