Have Roku Premiere, all of a sudden one day I turned on tv and pink screen. I purchased Roku Ultra, same thing. Tried new HDMI cable same thing. I haven't changed a thing on my tv or Roku. Have had Roku for 2 years. This only happens when I turn on ROKU. I have 2004 Sharp Aquos with 1 HDMI port, the tv works wonderful. I don't want to have to plug and unplug my Roku every time I want to watch tv. Anything else I could try? After I unplug and plug back in it works just fine. Any Help? or suggestions? (ps can't afford new tv yet-and this one works great like new). If no other suggestions, does anyone know if pugging and unplugging it everyday will it hurt my tv or the Roku?? Thank you.
