Fire stick, Blank kodi

Hello

i have a firestick running the latest software & kodi 16.1, everything works fine except kodi, when i install it initially it works fine then it will freeze or ill come back the next day and when i try open the app again kodi boots with the logo and then the screen goes black, force closing kodi from applications menu &/or clearing kodi cache changes nothing, i can see plugin updates flash up aswell as hear the navigations of the menu within kodi but its just black, i reinstalled kodi multiple times trying different custom builds each time & factory reset the stick aswell, with kodi reinstalled fresh it works for about an hour before this cycle begins again, only kodi is affected. Can anyone help as i cant send it back cuz i damaged the remote (altho it works fine)

Thanks.
