just got my micro-HDMI cable from AMZER for $10.99 and it doesn't work.i connected it to my HDTV and tried to play the movie Legion.the picture started but there was no sound.after a minute the screen would begin to flash every 10 secs or so.i stopped the movie and tried to watch something else but the TV would just stay black.when i tried to play Legion again it wouldn't start up either.my phone froze twice while i was trying all of this and i had to remove the battery and reboot.any ideas
