Need help: My car stereo is stuck on silent

The Pioneer stereo system started showing the mute sign when we drove over a huge speed breaker.

BHPian hrisig recently shared this with other enthusiasts.

I am facing a strange problem. The Pioneer DEH-P5090UB is permanently stuck in mute mode and I don’t know how to get out of it.

The system started showing the mute sign when we passed over a huge speed breaker. Initially I thought it was a small problem, but despite several attempts, the sign remains.

I showed it to a car garage, because depending on the person, a speaker might be short. I have my doubts about this angle as the short speaker should result in full power off.

Another store said to replace the entire main unit.

I don’t know what the truth is.

I also tried looking for clues in the manual, but couldn’t find any.

Please help.

Here is what BHPian VW2010 had to say about it:

Sounds like a grounding issue. Check to see if any wires inside or on the back of the device are open and touching metal. Just paste it if you find something open. Remove the device and check for open wires. Try saving and restarting the device.

Pioneer muting usually indicates grounding issues. Also, this symptom occurred after driving over a bump. Chances are that a wire is disconnected and either shorted or grounded.
