I have inherited a Finlux TV with Android TV. It is a cheap TV that was returned for service at the dealer, and since the dealer could not sell the TV, my father got it for free and I have since tried to fix it, but without success.
I think there is a major bug in the software/launcher. For some reason, it is impossible to open settings or any apps. Every time I try to open something, it goes back to the "Start" page on the launcher. I also can't open settings and reset the TV for the same reason. I can't practically do anything with the TV - all I can do is switch inputs. I also can't download any apps because I can't open Google Play. I can't think of any ways that I can get the TV to work. Do you have any suggestions?
My tentative solution is to use a Chromecast with Google TV, but it would be nice if I could get the TV's own software to work properly.
FYI, I have experience with ADB and flashing, but I can't find any firmware online, and I also can't enable ADB, since the settings app doesn't work.

Buy a decent Android TV box, and use that for your TV needs.
