I bought a new roku express+, created a roku account plugged devise into wall outlet and hdmi 1 port on my Sony Bravia. Turned my TV on and switched input to hdmi. TV automatically powered off. When I powered it back on it gave me a black screen. Unplugged the roku from hdmi and still got black screen. Unplugged TV from wall for 60 sec. and turned back on- still black. This was yesterday. Today tv turned on normally. I took a different usb to ac power adapter and cable and plugged in used a different hdmi cable and plugged into hdmi 2 port instead of hdmi 1. As soon as I switched input on tv to hdmi 2 I caught a split second of something come on screen and then same thing happened. Please help
