What button on tio of speaker do I push to shuit speaker off?

Have your son "play" with it again, or at least have him show you what he was doing when it "fell" out, he may have stumbled on the technique, but chances are a tab has broken off meaning it should be easier to remove now. Good Luck!

What make and model camera do you have?

Not flashing when you push the test button strongly indicates that the flash unit needs to be serviced.

Some radios have phone buttons that mute the speakers so you can talk on the phone. If you have Onstar and no active subscription it can also mute the radio thinking you are trying to talk to Onstar.

Well what the **** were you doing washing it *****. All you have tio do is just ******** with it it might fix your problem. But you will have a white screen.

The speakers are to close either to a printer or the monitor this due tio the model of the multimedia speaker system.

sometimes when you push the cable in i have seen folks get the cable into to far and then the conduit part is inside the connector also and the button will not come back down, make sure you only have the striped part inside the hole. if that does not work you might have to take a jewelers flat screwdriver and pry it down a little, either one should work. if not then either take speaker back to factory if under warranty or remove speaker and change the button. try the first one then the next one them the two common ones. good luck and let me know.

Many times someone will accidentally push the wrong button, or some remotes have tio be re-set when batteries have been removed and the code needs to be re-set. Go to remotefinder.rca.com/default.aspx?site=rca for your code. Sometimes more than one code is given for an individual remote. All must be tried until the proper one is found.

Check to see if you have sound by selecting 5 chnl speaker setting buy pushing the program button on the amp. you should have sound comming through all speakers.
