There's actually a place for this kind of thing on the Internet, but that place is a traditional discussion forum and/or possibly a wiki.
Repair questions are complex; they often depend not only on knowledge of electronic fundamentals but also on domain knowledge or familiarity with a product, wheras questions on Stack Exchange sites (or at least the traditional-upholding technical SE sites) are supposed to be about general principles applied to context explicitly included in the question.
Not only do repair questions depend on product-specific knowledge, they also tend to accumulate a lot of "me too" and worse, "me too" with variation - because products evolve and this year's model is likely similar to last year's with a few differences. Or the brand X and brand Y are really made in the same factory. Or brand X is made in a different factory this year than last year.
Discussion forums shine for the deep dives into investigation, proposing and testing hypothesis, and discussing possibilities; in contrast SO is for things which can be concisely and definitely resolved.
Wikis thrive for ever-evolving inter-related topics; SO sites allow edits, but late edits get ugly - particularly ugly when, for example, something changes such that the answer that used to work for the version of something it was asked about, no longer works for the current version which keeps driving people to the question page. Is an answer that was correct when it was posted and accepted still correct when the world has moved on and the modern equivalent needs a different solution? Who knows; it's outside the design intent.
Really the issue is simple: Stack Exchange is designed to handle one specific sort of thing, and handle it well, by intentionally excluding problems which don't fit that model.
Stack Exchange is designed with the implicit awareness that there is a remainder of the Internet which is NOT Stack Exchange.
Stack Exchange is not the Borg; don't try to make it so.
(Remember the flop that was SO "documentation"? That's why we avoid mission creep)
