Kodi issue?

Ok guys I have an Xcody box running kodi 16.1. Well all of a sudden it wont work on my big screen tv.
I went on youtube and learned how to uninstall add-ons and then reinstall them (was using my computer monitor as my screen).
Once I reinstalled add-ons everything worked fine on my computer monitor. Hooked up my Xcody box back up to big screen tv and it won’t work?
Comes up with log error problems, no streams found etc.. Yet when I use my computer monitor Kodi works and I have no issues
