actually this is because you have fired a timer on the slide update

showSlides2: function () { if (!this.slideIndex) { this.slideIndex = 0; } var i; var slides = document.getElementsByClassName("mySlides"); for (i = 0; i < slides.length; i++) { console.log(slides[i]); slides[i].style.display = "none"; } this.slideIndex++; slides[this.slideIndex - 1].style.display = "block"; if (this.slideIndex > (slides.length - 1)) { this.slideIndex = 0 } setInterval(this.showSlides2, 2000); //< ------- here restarts the function, BUT inside the function 'this'; becomes the context of the timer routine and not the module.. this.updateDom(1000); // or whatever transition time u want. },

to fix it you need an arrow function to keep context right

see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions

but net

showSlides2: function () { if (!this.slideIndex) { this.slideIndex = 0; } var i; var slides = document.getElementsByClassName("mySlides"); for (i = 0; i < slides.length; i++) { console.log(slides[i]); slides[i].style.display = "none"; } this.slideIndex++; slides[this.slideIndex - 1].style.display = "block"; if (this.slideIndex > (slides.length - 1)) { this.slideIndex = 0 } setInterval( () => { this.showSlides2()} , 2000); // < --- was a typo here.. need () => { stuff } this.updateDom(1000); // or whatever transition time u want. },

@gismo2006 Hey, honestly if it wasn’t for the fact that you mentioned changing tvservice to vcgencmd I’d never have figured it out! Your brief commend put me on the right path to getting everything working, thank so you much!! If I run into any problems with vcgencmd in the future I’ll be sure to pm you :)
