The radio will turn on but there is no sound. All the wires are connected and look to be in good condition. Any idea what could be the problem?

The volume control on your radio is called a potentiometer, which may be going bad. It works better when its warm because materials expand as they warm up and make tighter contact with each other.

It is also a possible a bad wiring connection exists. Poor contact will cause static, poor audio quality and intermittent output.

Your radio will have plug type connector(s) Your speakers will most likely each have two wires with single female spade connectors of different widths (keeps the polarity correct) the wire with the stripe (of whatever color) will be connected to the negative (-) speaker terminal.

So you need to check all the connections, one is making poor contact.
If both speakers (assuming you have two) sound good or bad... then start with the plug connectors for the radio and any independent black ground wire coming out of the radio.

If one speakers sounds okay check the connections on the other one. You check the connections by carefully pulling the speaker wire off of the speaker and then carefully pushing it back on making sure it feels tight and secure.

PS: If you pull the fuse for the radio, the radio will have no power and will not work. The radio coming on proves the fuse is good.

PSS: Your owners manual should provide lots of information on your sound system components.

Hi,

Initially, pls verify the splicing/wiring:

If verified and still no sound, either:

• setting configuration (menu); or
• internal fault of the Pioneer unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

When you shorted the CB ant cable, you may have burnt the ground wire in the headset connector

possibly the speaker harness in back of the radio came loose, and fell out. remove the radio, and check the wiring harnesses.

Hope this helps

I hope you used an adapter to plug into the factory wires .... and if all your connections are correct ... I would verify that you have a good ground (touch a wire from a good clean bare metal directly to the radio's metal case) .... and check fuses .... Radio and clock fuses .... certain expeditions have amplifiers and subwoofers built into them and may not be compatible with your radio .... need more info

You could always check the fuse first if that was not done. Then check the connection at the radio. Good luck

Radio and on star does not work what should i do??

All the battery does is hold your presets...radio should run fine with no battery at all...just annoying when you turn if off and all presets are gone.

Sounds like your off-on switch may be gummed up from sitting too long.

Have no idea what you mean by "shorting out the faceplate", that really doesn't sound too good!

Hi,

Either the radio's output ICs are fried or speaker/wires needs to be checked.

Incidentally, there are some higher end versions that has an Infinity Amplifier (P/N: 56038407AD) powering the speakers and not the radio (alone). If so, this amp needs a trigger on from the head unit to work and therefore, the trigger wire/connection must be checked. Otherwise, it may likewise require an internal check.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

confirm good wiring condition of celling speakers and disconnect it and connect it again-keep good ventilation around.
