Amplifiers started chirping then system stopped operating.

This models has history of AMP has to be sent out for after market repair at $700 or replacement from Lexus at $2600.

Rash of comments in forums with Lexus Mark Levinson AMPs with this issue.
The sound system stopped working. Later it begin working again. And then intermittently would change stations on the a.m. satellite dial. And then has stopped working entirely
Was traveling, when out of the blue, music replaced with loud chirping. Tried everything, but nothing would stop the noise. Ended up pulling the fuse. Over $3,000 to fix ... sad. Now listening to Pandora on my cell phone. Wow ... real Lexus / Mark Levinson quality!!!
I get no sound from my radio, CD player or auxillary... You can't hear the GPS prompter voice either and when I go to my audio settings The treble and bass settings are stuck to the far right
I pulled the amp out of trunk. Amp is on the far right side of trunk. You will have to remove the covering It's under car mat. I sent the amp to radios and more.The purchase repair was listed in eBay.The cost for the harman Becker amp repair was 725.00 So far the amp has been working perfectly.
Well driving the Radio would turn off then turned back on again then come back on again. Took to Lexus several times they complain that it's not an issue very intermittent finally replace the amplifier thank heavens for warranty
With no warning while the radio was on, a chirping sound was heard from all speakers. Turning the radio off made no difference - the chirping continued uninterrupted. My local Lexus dealer diagnosed the problem over the phone. Obviously, he was familiar with the symptoms I described. Subsequently, an examination by the dealer's tech confirmed the problem, and I was quoted a repair bill of almost $1,000 for a reconditioned amp.
my radio just stop playing and started chirping. could not turn off the radio to discontinue the chirping.
