where do you get schematics of consumer eletronics?

Hi as a title

sometimes I can find something online, or fishing out something from the patents of that product

I know that they don't usually release those for the public..

but there is not any source where are usually sorted?

Most of the time they're not made public to protect patents and design IP.

Actually, the datasheets are a lot more revealing than people think they are, if you know how to read them. For example, a listing of assembly instructions and their detailed description for any given processor is enough to redesign that processor because, in one sense, the listing of instructions and their detailed description is the schematic of a processor.

Even for non programmable devices, the user available datasheets usually contain "equivalent circuit" descriptions. These are not diagrams of the exact circuit used, but they are a close enough approximation that it can be substituted for every use of that product, and with the appropriate skills, you can use the spec list for that product in tandem with the equivalent circuit to reverse engineer a likely solution. The easiest reverse engineering example I can think of where this method would apply is a CMOS compatible 555 timer.

In the case that the manufacturer announces to the world that they are conforming to some public standard(s), that's even better because, if you can get your hands on that standard, you have an even more detailed description of the requirements that the design must meet. If you can get all three of these for a product, then you literally have an excruciatingly detailed description of exactly how that product works.

On the other hand, if we are talking more on the datasheet side, as in "How do I use this chip that I purchased", there are almost always atleast one, and possibly two (in the case of programmable devices) datasheets available to you, otherwise you couldn't actually use the product. Check for your product on Digikey, if you can find it there then there will usually be a link to both the manufacturers page and the specific datasheet(s).

No, as a title and description, I'm talking about schematics of consumers electronics

This. But what are you looking for? You have a product number or something?
