Very informative . How do I download internal schematic..

Mine did the same-- did you ever figure yours out?

hi, seems like you may have a faulty aux jack socket(if the socket is mounted onto the face) or you may have some dry joints on the socket, or even a cracked pc board around the aux socket connections. also try cleaning the face connection pins both on the unit and on the face. if you not technically minded, check out you jvc repair center. cheers!

The reset switch is usually behind the faceplate (there should be a tiny hole).Using a paperclip (or fine tip pen), gently press and hold this switch in, for approx. 3 seconds.

push the color button when the display light's up you can choose between one color for the button or one color for the display by turning the volume button and choose which color fit's your liking when u find your color push the volum button. that should help you out on that part.

To set the time for this unit, press and hold the menu button. Press the track advance button ">>>" til it reads clock H, then rotate the volume knob to adjust the hour. Press the track advance button again, and it will read clock m. Rotate the volume knob to adjust the minute. Then press the back button and it will take you out of the menu. The color can be adjusted from the button that says color just about the menu button. You can adjust the color of the screen, the buttons, or both. Hope this helps
