I have the exact same problem as orginal poster. GX 2007, and I belive that the amp is the same model. My service told me that I may require replace the amplifier. However, a couple of days after the audio came back. it was working fine for a couple of days. Now sound is being dead again. I asked for estimate again, see how much they are going to charge me. and I will try to negtiate with them since the latest ml amplifier seems to have troublesome. I will update the status as it progress.
