Fault with Apple Watch 5
Hi my Apple Watch 5 has developed a fault where the screen shows only cyan. If I try to power cycle it now flickers and then continues to show a solid cyan colour. Any ideas??
Apple Watch Series 5, watchOS 7
It sounds like it might be a hardware problem. I suggest you contact Apple Support.
