We've had Denon AVR-1911 radio/amplifier for fairly long time now, can't remember exactly but I'd guess some 10-15 years. Lately its use has been, well, occasional, at best, as sound from TV has been "good enough" for almost all of the time.
During the pandemic I bought "ticket" to Nightwish internet performance, and obviously would have liked to to listen that on the stereo set. Alas, no sound. Sound system starts up, but is completely mute. It seems like all audio sources are there (HDMI is detected for example) but no matter what, there is no sound coming through the device.
At the time I had no time to troubleshoot it, so I just shoved it in a cabinet at home, and it has been sitting there for year or so. Now I finally had some free time to work with it, so I took it to work where I have much better tools for this kind of work (I had found service manual for it so I could try to figure out what's wrong -- these damn things are seriously compicated to work with, at least without any help)
Before I managed to get properly started, I
dropped it
while trying to get all dust out. At first it seemed that it fell on rear corner, bending metal chassis and nicking small piece out of one PCB, but now it went to error mode almost immediately when started up. Crap.
On closer inspection I noticed that a PCB at very opposite corner it fell on was also cracked (on picture I apply pressure it to allow seeing the crack more clearly). No idea how, but that certainly qualifies as huge issue. Huge enough issue that I immediately gave up. I might be able to bodge traces together, but that goes way past work amount I was willing to spend -- and the drop might have caused other damage too I've yet to notice. PCBs in it are soldered together, so it's major effort to even take boards out!
Too bad, this might've been interesting to diagnose otherwise. And if I were to use this, say, even weekly, I might be willing to put in more effort. But like I mentioned, when it's been a year and I've barely missed it, it obviously isn't that necessary gadget in our home right now.
