Hi,
Initially, have you tried a full hard reset? The reset button is at the panel at the back of the faceplate, bottom left side. Of course doing so will also erase all presets and user settings & configurations.
Additionally, pls verify that the multiple contacts pins are clean, free of corrosion and makes a positive contact with its mate at the rear of the faceplate. If the unit is used in a salty environment, it may be necessary to manually scrape of whatever blue green build up develops between the connector pins and the plastic insulator. You can try using an old toothbrush and WD40.
Further to check are:
1. the red, yellow and black wire are tightly connected where they are supposed to be connected. If the unit is used onboard, it might be to your advantage to likewise check the grounding system;
2. one of the rear connector is for a remote, pls likewise check that none of the pins are shorting and no presence of any corrosion.
If problem persists, it may be necessary to seek the services of a qualified professional as this involves opening the unit up and tracing the circuitry of the logic/controller circuit.
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.

Possible Blown Speakers?
Any speaker, if abused, can be blown. And if overdriven with dirty power at extreme levels it is not uncommon to burn out the voice coil. You might also want to check out the speaker surrounds. If they go, the speaker works but sounds lousy.
Localize the problem by hooking up two known good working speakers and see what happens. If they also do not work properly or sound like cr-p then the radio is at issue.
