Green screen

Thanks for your help! I don't think so I have another box that works on the same HDMI.
When I first hooked it up and plugged it in I just got a green screen. I would like to fix this or upgrade
any ideals???
 
thanks guys, I got it. put a toothpick in the a/v hole and hold it there a few seconds and it will reboot.
if you don't put it on the home screen when you are done it will freeze up again and you have to
do the same thing again.
 
this thing is a pain in the ass now it comes on but is stuck on android if I reboot it for thru the a/v slot on the back it
says unfortunately Google Play Store has stopped working--any ideas??????
 
try disconnecting the power first, then hold that reset pin and don't let go of it. Then connect power and still while holding that reset till it boots.
