Hi David,Thank you for using Just Answer my name is ***** ***** I will help with your question. Please could you let me know if there is no sound on the cd function?
Hi David,I think that either the pre amp module inside the radio or the main amp itself has blown. Would you be looking to repair the unit yourself?Do you have any amps attached to the amp outputs of the radio.
It is unlikely to be cost effective to repair a new unit is 79.99. It would be worth double checking the speaker wiring and if possible disconnecting the speakers one by one just to eliminate a faulty speaker. A faulty speaker may cause the unit to shut down the amps I don't know if this model has output protection but I would try that before I brought a new one.https://www.caraudiocentre.co.uk/product_m-pioneer-deh-x6600dab_p-31369.htm?gclid=CjwKEAjwqpK8BRD7ua-U0orrgkESJADlN3YBLAxSwxl0pstsaL_3-1tZnojJaAAXeD9jG79Xyv9b3RoCls7w_wcB#
