Nexus 10 won't start after battery change

[Android Central Question]

I have changed the battery after the old one was only lasting about 1 hour. I thought the job had gone satisfactorly and left it on charge overnight. When I pressed "start" in the morning it produced the start vibration but there was no screen activity. I assumed I might have not properly reconnected the display ribbon connector and went through the whole process again, disconnecting and reconnecting all ribbons. Now I can't even get the vibration. Any constructive ideas?
