    This is on kvt819. Driving on one raining day and the next thing I heard was a strange noise from the front spearkers.



    Then the display appeared on the screen since then.



    The brain box was sitting in the truck of the car. It looks like water got into the unit.



    I have cleaned out the unit and is well dry. Still having same issue.



    Any help will be appreciated.

What does the word "Protect" mean in the display? My receiver AG-D9100 works great and then quits and the word PROTECT comes up in the display. If I turn it off it usually starts right back up ok...for...


Something is shorting out and tripping a safety feature that protects the amplifier from damage.

try a few simple steps to see if the problem is internal or external.

First make sure that none of the speaker terminals have any loose strands of wire that could be grounding out the terminal and that no wires from the red terminals are touching the component or the black terminals / wires.

secondly disconnect all but one speaker test it to see if t causes the amp to go into protect do so for the other speakers until one trips the protect mode. If one of the speakers is tripping the protect mode it could be a damaged / blown component.

just for fun make sure your speakers are 8 ohms this can be found on the manufacturers website or in your manual. Its rare but some speakers are 4 ohm and they can cause amplifier issues such as tripping a protect mode.

You may have to evaluate the "value" of the receiver and determine if its worth repairing. Many shops will charge a "diagnostic" fee which may be $40 to $80 and remember that parts and an hours labor may not make good financial sense especially if you are talking a unit that is 5+ years old.

Hope this helps

Protect displaying


Protect on any reciever usually means that it has reached its maximum capacity of volume (known as clipping) and at the reciever is now automatically reducing the volume to avoid damage. This some times is triggered if the reciever was used hard and is now damaged so you would need to bring it to a repair shop. Sometimes its caused by a bad wire to the speakers, a short to say. Check all your wiring, make sure its not overheating and getting plenty of air. Some where its recieving a signal telling it to go into protect mode.

PROTECT DISPLAYED ON RECEIVER


This generally means you've got a short somewhere, and the received is trying to protect itself.

My suggestion is to disconnect all of your speakers at both ends, and reconnect them.

Most times this happens because a speaker wire is lose, and the positive and negative connections are touching each other, causing it to short out.
