Probably the amp chip. Common issue with the HK radio. Some options are after market replacement or Ironcrossaudio.com for repair of yours. They offer a $165 repair option through eBay or I believe it's $240 through their website. Put this number 141774600929 into the eBay search box to find their listing.
The amp chip costs about $5 if you have the tools and skill to replace yourself. It's the big upright chip at top of pic.

The sound board inside is broken, I had same problem and sent it to Ironcross audio  in N.C. Give them a call.
