@TomasZmuda Great! Thank you so much! option 1 only cuts 12v to the inverter, not the main board so should have the same effect as option 2 but if I can drop the relay it’s one less thing to power so with your help I will go for option 2 for sure :) thanks again!

Also note the light inverter to the left on the first image. Size on this depends on how many connections your screen have, in my case 4. But they know what you need based on the serial. Power adapter NOT included (12v, 4A)
