Pioneer head-unit stuck in mute mode!

I am facing a strange problem. The pioneer DEH-P5090UB is permanently stuck in mute mode, and I don't know how to come out of this.

The system started showing mute sign when we passed over a huge speed breaker. Initially, I thought this to be a small glitch, but despite trying multiple things, the sign remains.
I showed it to one car garage, as per the person some speaker might be short. I have my doughts on this angle as the speaker short should result in a complete power-off.

Another shop told to replace the entire head unit.

I don't know what the truth is.

I also tried searching the manual for clues but could not find any.

Sounds like grounding issue. See if any wires inside or back of the unit is open and touching some metal. Just tape it if you find something open. Remove the unit and see if there are any open wires. Try taping and restarting the unit.

Mute in pioneer generally point to grounding issues. Also this symptom happened after riding over a bump. Chances are some wire got disconnected and is shorting or grounding.

How do you normally mute the system while driving?
