No Sound

[jc5494126]

My 2007 RX350 has no sound coming out the speakers when I turn on radio, or CD. The control knobs and panels seem to funcation just fine, but I can not hear any sound. The audio from Nav system does work, though. This happened to me a couple times before. But those times after I stopped and parked it for a while, the sound came back. This time it seems I can not get the sound back even if I stop and park the car for a while. Anyone has similar experience?

Thanks a lot.

I've not had this problem but I have had a problem with the volume control button on the center console. Sometimes it just doesn't respond and just quits working so I have to adjust the volume using the steering wheel controls. I wonder if anyone's had this issue, either?

I am having a similar problem, Lexus did diagnostics and said I need to pay over a thousand dollars to have the Amp replaced.. I had the amp sent off and they said my amp hooked up to another car works fine. The place also sent back and working amp which has a similar problem in my car.. I have been told to check the wiring and the fuses.. thats next on the list..

I have just bought a Lexus rx400h 2006 with Mark Levinson Audio system which had same problem. The person I bought it from said it was working fine till he got the Battery changed. So if your Radio comes on but no volume or volume stays on "0" on display even if you turn the volume knob or steering wheel volume controls then check my steps below.

In my case it was 30amp "Amp fuse" in fuse box was blown. I had a spare fuse that i replaced and radio started working.

Me and all my family members had gone on so many forums to find out the solution for this and here is my conclusions below.

1. You need to check all fuses in fuse box, especially "Amp" fuse then "Radio/ Rad" fuse then someone mentioned "Tel or Tell" fuse.

2. If this happened when Battery was replaced then disconnect the Battery and reconnect (Assume you know basic rules for disconnecting/reconnecting battery...if not quick search on the net will help you) after cleaning the terminals and other connections that are connected with main terminal cables and ensure all connections are firm tight (this has resolved the issue for some people) if you still have the same problem after reconnecting the Battery it might be worth checking out the Fuses mentioned in step 1 again. If they are all fine then...

3. Check Amp cable to see if this is damaged and causing the Battery to go flat. It might be catching ground connection or some other cables and blowing up the fuse. If this is the case fix this issue and recharge your Battery and reconnect it (if your car Battery is new and was replaced recently or otherwise replace it.)

4. If your car Battery is old and going flat often then replace the Battery however you need to figure out why your battery is going flat. It could be that Amp wire is getting earth/ground connection which  could be blowing the Amp fuse .and follow all 3 step above.

5. If you have done all of the above and you still have the same problem then apparently pressing on the left of the radio body has fixed the issue for some. I am not sure where exactly as mine wasn't this issue. On other forums it has fixed it for some people. Apparently hot weather or if radio was pulled out before can cause a loose connection inside the radio (if you are very good at it you can open up the Radio and check all connections inside but you may not have to go this far).

6. If all of the above fails and you are now sure that Radio unit or the Amplifier is faulty then replace them by buying the same from ebay or other places Or resolder circuit board connection in the amplifier/ woofer and radio unite (mostly it is amplifier/ woofer which is in the boot/back of the car) but i don't think you will get to this stage but some people have replaced amplifier and it has fixed the problem and others have replaced the Radio.(your own diagnosis and gut feeling about what might be faulty and depending on what is the cheapest option for you to go with first if you are unsure). If you have have bought one of them and still facing the same issue then buy the other and replace and hopefully you can sort it out and sell non faulty product or keep it, it's up to you.

Oh yeh... check for loose connections in front drive and passenger footwell

I hope this helps others.

Good luck.

I have the sam problem with my Lexus RX350 sport 2018. The volume adjust doesn’t work as well. I just bought the car 3 years ago and the battery is still good. Anyone give me an advise please. Thanks

Doesn't your vehicle have a 4 year warranty? This issue would be unusual with such a newer vehicle like yours. Our 2006 never had this issue.

Hello good people. I have a 2007 Lexus RX350. There is no sound, no noise coming out of my speakers. The stereo turns on and I can adjust the volume(I see the volume goin up and down on the screen) but there’s no sound. 
The music played and then it just stopped for whatever reason.
I tried replacing the fuse, both radio and amp fuses - no lucK

I ordered a used amplifier. Replaced it - no luck, still no sound.

Maybe the amplifier I got is also bad. But maybe there’s a different issue? How can I figure out what’s going on?

The car has a aftermarket android stereo installed.

Thank you!
