2008 LX570 no audio

[cutiger1972]

My audio died recently. Ran the system check diagnostic and audio shows no connection. See photo for reference. I’ve removed and reconnected the head unit, DSP, amplifier and receiver. The fuses are all good. Is there something else I should be checking? Is it a matter of picking up a used receiver? Thoughts? Thanks for your help!

I'm having a similar issue on my 2014 LX570. Checked all fuses, all good, ran diagnostics, no codes/failures. I've reseated all plugs and connections within the dash, reached under the passenger seat to the RSE module to do the same.

Does yours show volume adjustment on-screen?
Mine does not

Does yours show audio adjustments (balance etc) in a centered fashion?
I've seen some situations on the web where an amp failure showed those levels maxed (all the way to the right and rear) and not adjustable. Mine shows centered.

I've seen multiple people mention United Audio doing repairs on the amp, but also have seen several posts mentioning the amp repair did not solve their problems. Similarly, the RSE module (multi display controller? under the passenger seat) seems to have similar symptoms when it fails, but I have not turned up much on resolving this failure.

I had the same issue and had to replace the headunit. My experience is here: LX570 Audio/Electrical Gremlins - https://forum.ih8mud.com/threads/lx570-audio-electrical-gremlins.959977/post-14119217

Thanks for sharing.

FWIW my wife's 2017 NX300H has same issue, no audio. I also suspect the head unit need or amp needs replacement, which is sounding like a pricey fix. I wonder if this issue is common in Lexus and Toyota's.
