Audio Systems: STOCK RADIO, ford radio repair

Question
HELLO

I HAVE A 1998 FORD EXPLORER WITH A STOCK STEREO AND SIX PACK CHANGER.

THE RADIO DISPLAY SEEMS STABLE MOST OF THE TIME BUT SOMETIMES GOES OUT IF YOU TURN THE VOLUME KNOB!

THE REAL PROBLEM IS THERE IS NO SOUND AT ALL!

THERE IS WHAT LOOKS LIKE A SYMBOL OF HEAD PHONES IN THE DISPLAY.

I HAVE CHECKED THE TWO JACKS FOR HEAD PHONES AND THEY SEEM TO BE OK!

THE RADIO SOMETIMES APPEARS FUNCTIONALLY NORMAL.

YOU CAN ADJUST CONTROLS AND CHANGE STATIONS,BUT SOMETIMES IT APPEARS FROZEN AND NOTHING WORKS EXCEPT THE DISPLAY.

NOT SURE IF THIS SYSTEM HAS FACTORY AMPS AND THEY ARE NOT WORKING OR IS THIS RADIO JUST PLAIN GARBAGE.

AT NO POINT HAVE I HEARD ANYTHING FROM THE SPEAKERS BUT NOT SURE I WANT TO REMOVE THE SYSTEM AS OF YET WITHOUT TRYING TO FIND THE PROBLEM.

I WOULD REALLY BE GRATEFUL FOR YOUR INPUT.

THANK YOU
RICK

Answer
There is no way to turn on and off the headphone form the radio, the switch for that is at the rear DVD, if you don't have one most likely the radio is defective and will need to be repair or replace
yes you have a factory amplifier
