DS8500/12 issue, sound leds blinking

[Laurent]

After 2 weeks without use and remained plugged (holidays), my DS8500 does not recognise any iphone or aux.
When plugging the iphone it does not charge (and no music), and +/- leds are blinking quickly.
When plugging an AUX IN, no music and +/- leds are blinking slowly.

Is there something to do?

Did you try this?

unplug the device from the power supply,
wait for five minutes,
plug the device back into the power supply, and
switch on the device.

Hello Oscar and Kwinnie,

It blinks yellow/orange (same color as before when it worked)

I tried to unplug, wait quite a long time (to avoid electrostatic issues) and plugged it back but it still doesn't work.

I also noticed that the Iphone is not charging when plugged.
I tested the 18 volts charger and it works.
