Is there a way to test the existing display? I made mistake of swimming in watch and it went into a continual reboot loop before it quit doing anything. I've got a replacement battery and installed it pretty easily but even when everything is put together except the back screws, nothing happened on the display when I put it on a known to be working charger. When I compare the appearance of the display connector and the slot on the motherboard to the pictures in the tutorial it looks like there is some corrosion or the likes there that I am working on removing with Deoxit DN5. But I am trying to sort out if the display itself is damaged or if the bit of corrosion there is keeping it from powering up. I have a voltmeter and the battery seems to be putting out the power that it should be.
