Stereo quit working but other functions fine (12 Viewers)

[CloudCity]

I'm not able to hear any music from my stereo (CD/Cassette/AM/FM/AUX) and only hear a repetitive light pop sound coming from my speakers. It sounds almost exactly like the end of a vinyl record how it just keeps popping after the song ends. It does this if the audio system is on or off. This is the Mark Levinson system on my '04 LX 470.

I can see all functions on my screen fine, and when switching between the CD, tape, and stereo they look like they're working with tracks counting, volume indicator showing, etc., just no actual music comes out. My climate nav, etc., all works fine.

I have the Grom setup that's an AUX-in only, no head modifications and have had this for several years. I can't switch to the AUX by hitting the disc button however, so unsure if this is somehow a Grom issue or a head unit issue. Is it the amp?

If have a way to easily do it I would check your battery. I had this happen a few years ago and the next morning it wouldn’t start. Replaced the battery and everything worked fine and no problems since. However, I can’t remember if I had the popping sound you describe.

look into the amplifier under the passenger seat
