Answer to: replaced screen - now it vibrates, but won't start upI'm having this problem with my iphone 5c. The screen cracked so ordered a new one. Ive just gone to replace it and now neither screen works. There is no apparent water damage or any damage with any connectors and as such its very weird. I thought the battery may be dead but thats not the case. It simply vibrates every few seconds. What do I do?
