SOURCE: no sound
you simply have a speaker shorting in your car. Either an old speaker with a bad voice coil (short) or a speaker who's contact(s) are touching metal. This type of short or grounding will cause the internal audio amplifier to shut off to protect the radio's output circuit. To diagnose which speaker is the culprit, you'll need to disconnect all speaker leads from the radio and one by one re-connect them until the output shuts down again. The safe way to check is with a voltmeter. If you connect one side of your voltmeter to ground and test each speaker wire lead for continuity, you'll hear an audible "beep" whe you find the grounded wire/contact. A professional car audio shop can diagnose this for you if you're still having difficulty. Hope this information was helpful.

Check your speaker connections if you still have a problem check the radio settings. You can view the manual in their web-site.

Usually with this model, when all else works, and there is no sound, the internal amplifier IC is blown. Smell the back, and see if it smells burnt. It may. It does not always tho. The IC is a PAL007a or something similar. It's kinda hard to replace if you aren't skilled with soldering, but it can be done by any decent repair shop. Also, test to see if there's a signal on the RCA's, if there is, you can forgo the internal amp, and get an external one. (it will require running speaker and power cables, but if you really like the head unit...;-)
