Onkyo HT-R530 has problem with headphone jack

These are quite easy to fix: just close the positive bar (the one in the middle of the plug entrance (jack socket), which make contact with the positive of the plug itself), by bending it just a bit, so it is tighter and closer to the negative side. You know what I mean, so that when you insert the stereo headphone plug into its socket, the positive is making a good contact.

Also, make sure that the two or three wires are all secure and well soldered. If not, just reinforce their soldering. And double check at their other ends (the wires) to make sure also that there is no problem. (The worst that can happen is that a resistor or the op-amp is burn out, then you'll have to replace that small part.) If you do need parts from Onkyo, by giving the model # of your receiver, they should be able to get you the right part from the schematics.

I don't think that you'll need a new part, I'm pretty sure that you'll fix it.

If not, get the headphone jack sucket from any older receiver or component that you don't use anymore, and just get that part out, and just reinstal it in your Onkyo receiver with some nice brand new soldering. That should be super easy for you because of your technical background.

Good luck & keep me inform of your progress,

Crap, I have the exact same receiver and am experiencing the exact same issue.

As someone who uses headphones 90% of the time, I guess I need to start taking soldering classes.

Yeah, yeah....well, just let it be a reminder that somewhere, sometime, someone else has the same problem you've been through.

I really love the receiver too, btw...but it's apparent that they didn't make the headphone jack as well as they could have.
