It’s a difficult subject, and there is (if the situation here in the UK is anything to go by) no simple solution.

One issue is that, because of the way that tech devices are made these days - to fit so many functions into a small space - replacement of some of the components can be very difficult. For example, the main processor is likely to have 250+ pins on a soldered-down surface-mount device, with a fraction of a millimetre between each pin. Devices like this are difficult and time-consuming to rework.

As a result, few people want to repair, because there is so much uncertainty about whether repair will be economically viable. Repair shops much prefer to work with older electronic devices where there is space around each device to allow you to work.

So, while there are definitely electronic repair shops around, many will be non-commital without knowing with some certainty where the problem lies. As an amateur, I’ve repaired a lot of electronic equipment over the years and I guess I have around a 60% success rate. That’s Ok if you’re just doing it for yourself - it would be unacceptable as a business!
