Ever since the latest android TV update for my Philips 43PUS6401 (says version 8.0.0 in settings) i've had an intermittent problem with both kodi and netflix not playing the video just sound, its usually fixed by rebooting the tv, but its pretty annoying. I can get round a reboot on kodi by turning off hardware acceleration, then the video appears, but the video isn't as smooth.

Wondering if anyone else has had a similar problem or if my tv has a GPU fault or something
