Klipschtastic Posted March 28, 2015 Share Posted March 28, 2015 (edited) I sent my Onkyo A9050 amp in for warranty repair because the front auxillary jack stopped working along with two inputs in the rear. After three months I received it back only to find that now the treble control does not work either. It sounds as if the treble control is turned all the way down. When I put it on pure mode it sounds right. I really don't want to wait another three months for this thing to be repaired again. I have limited technical knowledge but is there anything I can check to try to diagnose or fix the treble control myself? Thanks Jon Edited March 28, 2015 by Klipschtastic Quote Link to comment Share on other sites More sharing options...
minermark Posted March 28, 2015 Share Posted March 28, 2015 Just got it back from service eh ? Still not right and still under warranty i assume. What i would do is call them up and tell them your story, i would then ask for a trade-in allowance maybe even for an upgrade. Finding the right person to talk to on Onkyo's end could be your biggest hurdle. The reason i say this is, this will likely not be your last problem with this critter. If you get inside the unit, you may void warranty and any chance of trading it in, then you own junk. make sense? 2 Quote Link to comment Share on other sites More sharing options...
Klipschtastic Posted March 28, 2015 Author Share Posted March 28, 2015 Was under warranty when I sent it in. Not under warranty anymore. They caused the problem with the treble control when they worked on while still under warranty though. Ask for a trade in allowance? You mean a new replacement?

Klipschtastic Posted March 28, 2015 Author Share Posted March 28, 2015 Thanks Mark, I will. The unit will probably never be reliable anyway after being shipped around and worked on so much. 1 Quote Link to comment Share on other sites More sharing options...

Maybe it was built on a Monday, we all get one or more in our hobby. Quote Link to comment Share on other sites More sharing options...
