Hello! I picked up an oldish Onkyo receiver from a thrift shop to use as a garage system. I hooked it up in the store and it seemed like the speakers were working, but when I got it home and set it up it turns out that only one speaker channel is operating at full volume. The other channel is pretty quiet, but will pop up in volume when I crank the volume.
Searching a bit online I found out that relays are a common culprit for this problem and it sounded like it might be possible to remove the relay cover and clean the relays without de-soldering the relay from the board.
So I located the relay and tried to pop the cover off, and I actually pulled the relay off the board breaking a pin in the process. I obviously have no idea what I'm doing. So then I tried to open the relay to look at it and I broke the case that it is in. Inside it looks to me like this thing isn't really meant to be replaced at all.
Is it possible to find a replacement for it, or am I out of luck and just need to scrap this thing? I am looking to the experts to help me figure it out.
I should also say that I'm not even sure if the thing I pulled out is a relay. That is how much of a noob I am. I appreciate any help here, I don't know where to look for a replacement, or how to specify what I need.
I'll see if I can post a picture, but the outside says that it is a Takamisawa unit. It says 24VDC

Yes that is a relay, but doesn't look like it is openable. WHy assume it is the relay? My first suspects in an old receiver like that would be the switches on the front. A "tape monitor" switch, any mute switches, even the EQ in/out switches.
While the internet is a wonderful, vast source of information, it also is a source of making problems worse, along with hoardes of misinformation and dopey suggestions.
The inexperienced are the most prone to its dangers.
Its a common sealed relay type - the 24Vdc etc in the photo is the max switchable voltage for the rated current. Somewhere else on the case is the coil voltage.
But as Enzo sugests, without testing you do not know what has failed. At this stage I would solder a jumper across the pcb pads for the contact pins to make sure the relay was faulty.

To help us people the manufacturer also mentions a type number. You could of course search for that type number and find the right relay in 1 second. Just saying...
With not enough knowledge and skills working inside electronic devices is like having a nurse flying a 737 Max googling how things work during the flight.
