I bought an Amazon Fire Tv box yesterday. All was going well, installed no problem, downloaded some apps. However then I noticed there was a software update which I installed. However at the end of the install the screen went blank and i can get anything on the screen. I have tried the reset pressing the right and back buttons together. It seems to go through the motions and i get the Amazon sign come up, then it shows the update install and screen goes black again. Has anyone else had this problem and if so how have you sorted it out? Any help appreciated.
