Hello,

I acquired a loaded 2008 LS460L a few months ago as a project car with only 70,000 miles. I fixed a bunch of little things and am looking to sell it, but the audio has suddenly died. As some other users are reporting, my symptoms are:

-No audio, even through navigation or for touchscreen beeps
-Volume adjuster won't do anything
-EQ has the treble and bass turned to maximum, with the mid having disappeared

I bought a refurbished amplifier and installed it, but to no avail. I then replaced all of the fuses related to the amplifier (three total), and still nothing. Do I need to initialize the new amp, or is the amp not the issue? The only other thing I can think of is the head unit. Thanks in advance!

Did you change the main fuse near the front passenger foot area? I believe it is 30 amps. I'd check it again and see if it is blown.

Yes, I replaced that one. It actually never blew, but u got desperate and replaced it just in case.
