I did the repair to clear out some dust and glass from a blown lamp. After putting it back together, I get lights most likely from no power at all. Do you think the next step would to be take back apart and make sure everything is connected correctly? I can be reached at jaspercloren@gmail.com or I will check back on here.

Thank you for all your write ups, they are very nice. I may suggest to get a closer view of the screws/bolts in case someone misplaces one.
