My radio audio and CD audio has disappeared on a 2004 ES-330 with nav.
Nav audio continues to work.
The screen has stopped beeping when touched, the volume control does not make the volume numbers appear in the upper right of the display, and I can't change the equalizer or balance settings, both of which have reverted to their default center positions (not where they were when it was working).
Pushing the volume button toggles the "AUDIO OFF" display.
The radio itself seems to be working - presets are there, I can change stations, the embedded data displays, the FM Stereo indicator lights. Also, the CD changer changes CD's and the single player changes tracks.
It just won't make a sound.
Since the nav audio works, I assume the amp works, and it's something else. Perhaps there's some "turn the amplifier on" trigger that isn't triggering?
Any help appreciated.
