Default Radio controls- FM AM AUX SAT turning off

My lower control board for the audio keeps turning on and off it seems like whenever i go over a bump it will turn off and eventually turn back on after hitting another bumps or just with time...becoming quite annoying. I can hit the volume/power button and I get nothing.

There are no lights on the AM FM AUX SAT buttons. Says to me there is a power issue..meanwhile the upper monitor portion of the dash with climate/gps screen continues to work just fine and has never had issues.

Let me know what you all are thinking, thanks!

Your radio face not working properly. If you recently work on the unit (fixing up the touchscreen) You should check the radio face to make sure it fully seat

Well, i have seen a few with that problem including myself. The control **** not working properly and end up with replacing it. Your problem is a little more cause no light for AUX AM FM SAT. It could be one of diode inside not working properly. Highly recommend you to fix the control face.

My 2012 IS 56K just started doing the same thing. A few times my CD would pop out unexpectedly. Yesterday the entire system would shut on and off seemingly related to bumps and the CD would just constantly pop out stopping whatever was playing. I look forward to comments. I have been very happy with this car and kept it pristine, with some nice improvements but I have to have audio available ;(

It is not the control face, seems to be a power supply issue to the lower board?

The bad part is I took it the local Lexus dealer which is a HUGE dealership here in VA, they had no idea what to tell me...well except to replace the entire radio/map unit (upper and lower).
