You have a point there. Recycling is a bit of a con. But the fact is, you are not going to fix this receiver unless you are very skilled and have a bench full of sophisticated test equipment. I have a pretty large array of test equipment, but I would be loath to get into a receiver. These are short lived devices. The parts probably are not available. The reason is that a lot of parts are only made once now, due to set up costs, and when the parts are gone they are gone. The life of receivers especially are not long, and yours is pretty much maxed out.
Service manuals are no longer issued, and so if you want it repaired you will have to send it to a factory authorized repair center. That will cost you far more than the unit is worth.
I am with you about electronic waste, but that is the way the system is geared. It is not like it used to be. I have gear working here going back over sixty years. That was a simpler time, and service manuals were easily available and the units were simpler and easier to work on than now.
You can resist all you want, but I gave you the correct advice. You won't fix it, and it is not worth paying someone to do it. That is the way it is now. So in the end you have to face facts. To change the situation will require a huge change of gear in the industry. I personally favor a modular design approach. However that would increase initial price, but make servicing and upgrading much more practical and straightforward.
But it all comes down, to I want it for X, where more expensive Y would be a better option in the long run.
