I appreciate the help I can get here, thanks to the experience and quality of many of those who contribute.
And when I want to add my share, I try whenever possible (or time permits) to give step-by-step comprehensive answers fashioned like a flow chart or guide, that make it easy for novices to find and understand the issue, and that I can use again as templates. Face it, we’ll not always feel like contributing valuable time, or repeating the same explanations again and again, just to see newcomers reiterate the same question a few days later - not just because they’re too lazy or in a hurry to research the previously answered questions, but also because the novices (who this website was first designed to help) lack the knowledge of technical terms to associate with their issues and thus are unable to search for and find previous discussions.
Which is why I’ve grown convinced, if I may, that troubleshooting guides must be at the heart of the Answers’ section and may be of the whole site, not just a low-visibility remotely accessible section of iFixit.
As Jessa and O.T. put it, there are so many ways we can direct people to those guides, but (again if I may) I’d "over do it:" from the main page such as adding “Troubleshoot Your Device” above or below “Find a Repair Guide,” add a tab next to Guides & Answers, and/or link from the devices’ repair guides, to "suggestions" that appear when trying to fill the tab for a device (when asking questions).
