Chosen Solution

I have just used the ifixit kit to repair the swollen battery in my Apple Watch. Unfortunately when i’ve put it back together, but before sealing the screen, I now have a screen which does not display the apple logo or other stuff. Instead it’s just a mess of multi coloured pixels. Have I broke the screen or is this damage to the rest of the watch, or have i just not put it back right?

take it back apart carefully, check your ribbon cables and the FTC connectors for bent pins. they’re VERY small so you may need a magnifying glass to do this. also check the ribbons for rips or tears. typically if something worked before and now doesn’t it’s a seating issue or a damage issue. hopefully just reseating everything works! good luck
