My first post has a picture of the tuner not amp. se attached for amp.

I'd like to report a successful amp replacement!! So, I sent the amp to United Radio and for $450 they fixed it. No idea what was wrong. Before sending it I was unable to figure out how to open it and look for obvious issues. Anyway, got it back yesterday, plugged it in, presto, music is back. Putting it back into place was much easier than extracting it. A trick might be that when removing it, after removing the two nuts and pushing the two white pegs in, push it further forward into the wheel well instead of pulling straight back and out. Anyway, that helped me. I haven't reinstalled all the trunk panels yet, that will be a chore. So the point is, anyway can remove the amp, United Radio and several others repair them for a flat fee. Not positive what Lexus would have wanted, probably $2,000.

Recently the music stopped. When I turn the ignition to position two I get one second of audio. When car is on, no sound. Is it the amplifier in the trunk or the radio in the dash? Removing the amp is challenging. So many panels and first the navigation. Got most of the way there and stopped, pending tips. I have no ability to diagnose the problem, but obviously the amp is getting power since I get one second of sound.
