Why is my right speaker channel failing?
This vintage analog integrated amp has an enjoyable sound, but for some reason the right speaker channel doesn't work all the time. (it's not the speaker itself, I checked)
Weird thing is, when I put pressure on the capacitators on the circuit board, slightly bending the circuit board, it usually works again…. only to stop working some time after.
Also sliding the volume control on the front panel to maximum for a brief moment sometimes does the trick.
I have no idea what is causing this.
I don't have the guarantee or puchase paper, sony won't help me.
And I'd like to fix it myself.
I've added a picture of the inside and marked in red the capacitators I press
and a link to an image of the front panel on
Both sides of the board are accessible, but I didn't really find a dry joint.
No apologies needed, even if I did already know what it looks like :D.
Still not sure what the problem is.
I tried bending this part (red circle in pictures) , which is crooked. I'm nog sure if it's supposed to be crooked.
Also thought it was maybe this thing (green circle), unsoldered and resoldered that, but to no avail.
Also, when i there is alot of volume, usually it works again. (like, when a laptop goes into the TV via hdmi, then via minijack/cinch out of the TV's headphone socket into the amp, and all volumes are set high) But so this got me thinking that maybe it could be something else?
