I replaced the screen on my watch, but the screen remains black and I don’t think the watch is turning on at all. I do not feel any haptics or anything like that. I don’t think the battery is damaged, but I suppose it is a possibility. The watch was smashed until the screen fell off. When that happened the watch was still turned on and I just let it die.
hello christian, put a watch on charger and check (try switch off, you ‘ll feel vibes). Often, during replacement, the connecting tapes are damaged or one of the connectors does not click properly. In such cases, you have to disassemble everything again and try from the beginning. Unfortunately, lately many of the new (replacement) screens for Apple watches are simply not working. Find a good repair shop, let them worry there.
Try removing the battery, and do a reset. Then reattach the battery. I’ve had many play up like this, then out if the blue, they’ll fire back up when put on charge. Sometimes the flex cable can be damaged. Also, you say you’ve replaced the display? If so, are you aware the NFC part need to be swapped over to the new display, as they’re paired with watch.
