List or database with causes of errors?

Is there a list or database with the causes of errors for DMG-01, Pocket, Advance, Advance SP ...? E.g. If errors appear in the font when starting the Gameboy Classic, it is often due to contact problems between the Gameboy and the module. In and out quickly a few times or cleaning contacts often helps. Does this also apply to the Advance SP, for example? If it has always worked, and suddenly such problems arise, is it also contact problems? Even if it works in another SP. No, it is not a device that I have on site, just an example from the Internet. It would be good to be able to look up all possible causes for every error.
E.g. this would be useful if you don't know whether you can repair a device offered on Ebay.
