Solved! Hitachi rear projection and android box

[Tahnee_1]

I have a hitachi rear projection tv. I ordered an hdmi/av cord so I could use my mx pro 4K, but the screen stays black. There's power to the box but nothing shows up on the tv. No start up, nothing.

You can't use a cord to convert HDMI digital video and audio to analog AV. You need an active converter.
