On the headphones it's all right. As soon as I pull out the headphone plug, the sound comes out briefly on the loudspeaker for about 1 second and then not at all. The problem occurred after trying to clean the radio with water. So I opened the unit and let it dry for 24 hours at about 27°C, without success. Then with a hair dryer I heated the 2 audio connectors specially, again without success. Finally, I unsoldered these 2 connectors but the problem is always the same: a brief sound then nothing.
Connectors are 8 PIN 1/8" 3.5mm Stereo jack Headphones Socket With switch PCB Panel Mount.
On the loudspeaker there is a small PCB marked PURE connected with 5 wires to the motherboard.
Does anyone have an idea for the repair? Thanks and regards. Lorain
