my radio just stopped playing one day after the warranty expired, ran radio internal diagnostic and have code 2017 open speakers, checked eveything I could think of but no signal is being transmitted to any of the speaker terminals. cant get anyone to repair or even to look at the unit they all say the same even harmon-Kardon only HD can replace the unit thats the lock on the market.anyone have any info.
other than no sound the radio acts normal,all controls respond.

Thanks
