I bought the ChromeCast and it works perfectly with my living room Television. I initially purchased it for my bedroom. When I tried connecting it to my bedroom television it detected it for maybe 3 seconds then the screen says NO SIGNAL. At first I thought it might be my HDMI but I plugged in my Xbox, my iphone (via HDMI adapter), and a DVD player, they all worked perfectly so I knew It could not be the HDMI. The weird thing is that it connects perfectly with my living room Television. They are both Samsung TV's and I called both Samsung and Google and neither could really figure out what the problem was. Samsung said if HDMI works with other devices then that the problem isn't with the TV, that it was probably the device. Google said that if the device works with the living room TV and not the Bedroom TV that the problem isn't with the device and that its probably the TV. Now I was just left confused and I can't watch the TV in my bedroom. Does anyone have any idea what I can do to fix this problem?
