I own a Yamaha DSP-A3090 Int. Amp. Currently, when I select an input source,manually or with the remote, the motorized selector will not stop on the chosen input. It will bounce thru all the available selections and stop where ever it wants to. If you apply a slight pressure to the manual input selector nob, it stays on the input you want. But the second you release the pressure, the selector will return to the random selection cycle. This gets old very quickly. I have contacted Yamaha technical services and they informed me they know about the problem, but have no replacement parts or incentive to correct this problem. I have reverted back to my old system, Yamaha DSP-E300 & McIntosh MA6200, to get by. I am not going to invest another $2500 on a unit that cannot be repaired after the warranty is up. What new equipment will closely match the abilities of the DSP-A3090, and also have a good record of reliability and be able to be repaired after a few years of good service? :help:
Hello,
Those symptoms sound quite similar to an issue with a small segment of 2009 Onkyo AVR's where they would switch Inputs on its own. The culprit was an IEC or Serial Cable, which are commonly used in PC's. However, the direct pressure making it work properly causes me to question if that is the issue.

And while I certainly understand your frustration, some brands are better than others in respect to keeping Replacement Parts. I would also guess there is a Repair Shop out there that specializes in Yamaha Repairs.
Good Luck,
JJ

Hello,
I am really surprised to read that Yamaha is acting in this way as they enjoy a stellar reputation. Good luck on the Contact Cleaning.
