SOURCE: Auxillary 2 function does not show up on my Pioneer DEH-P2900MP

first thing you do is turn the power off on the radio by hitting the off button . there is a button you have to hold in. it should be the volume knob. if not try some other buttons. you have to hold it in for about 4 seconds. then a menu should come up. if you scroll though and you can turn on and off the aux . if you have any problems let me know

Display back light problem

There are several baclkight bulbs (or may be leds)

Either the bulbs are burn out, or there may be a crack in faceplate PCB that is stopping the power from getting to the backlights. If all other buttons/functions work ok, then suspect burnt out bulbs. Expecially if there's a lot of use on the unit. The bulbs can be replaced by a repiar center, or by you if you have the skills.
