> it is in my view completely useless if it doesn't solve the problem.

Well, this is exactly the problem I'm describing: you're trying to solve the problem for one user when the answer is for everyone who could ever ask something similar enough to come to the page from a search engine. So ignoring the question and solving the problem might help the OP but it doesn't help anyone else who actually needed to know how to replace a lamp. In fact it's hurt them because now "how to move a lamp" is considered solved by a lot of people but the actual page with the "solution" does not contain one.

Yes I get your point, but again, in my opinion, if there's no Q/A yet for how to replace a lamp, the others seeking an answer should just ask that question specifically. The net result being both the original OP and the others are helped in a clear way. Unless of course someone comes up with an all-in-one answer to the original question laying out all possible reasons why there's no light. But that's the edge between way too broad vs specific question.
