Question about Kenwood DVD NAVIGATION SYSTEM Car Video Player
I have the kenwood navigation system in my 2002 honda crv. yesterday, i accidently left the lights on and ran the battery down. i had left them on for about an hour and a half, then jump started the car and ran it again. prior to that the navigation system worked perfectly in every way. since the battery was run down, it now doesn't display properly. audio passes through it ok, but the display is unusably dim and unreadable. i've run the car last night and today, it works fine and the battery seems to be doing fine. however, the kenwood system still has the display problem. is there something i can do to get this working again. i expected to perhaps lose my radio station presets, but don't understand how the display is still effected. did jump starting the car hurt it somehow? any ideas as to what about that situation would have effected the display?

I have seen problems in the hideaway (brain) where 8v reg circuit fails causing higher voltage(12v to 14v) to be on that 8v line. First component to fail is the Tuner followed by electronic volume ic. I have probably seen 6-8 failures where tuner fails. Fix is to replace tuner and replace open chip resistor in Hideaway box to restore 8v regulator to proper voltage. email@example.com

I would be willing to bet you have a 8v regulator circuit failure in hideaway Box. I have seen many of these units where a resistor opens and causes 12v instead of 8v to appear at tuner and a few other IC's. Usually But not always destroys tuner.

Had the same thing happen to me. All you have to do is use a pen or a paper clip and push the reset button located on the front of the unit. It cleared right up.

The unit appears to have been installed on the 12vdc connection that is on the same circuit as the the vehicle's ignition switch. This means that when the ignition is turned there is a rapid drop in voltage which cause the problem with your device. You need to connect the device to a 12vdc circuit that comes straight from the battery and does not connect to the ignition circuit. Now for another possible cause if the 12vdc you are connected to is from the battery and not the ignition connection. The battery could be dropping below 12vdc during the starting of your vehicle. This could be the sign of a malfunctioning battery, or a problem with the car's electrical system.
To test out if the battery ids dropping below 12vdc I would suggest connecting a voltmeter to the - and + of the battery and starting the car. The voltage should drop but not below 12vdc.
I hope this helps,

I bought a Kenwood KVT-815dvd player and got everything hooked up to only find out that it had a security code. The problem now is that I got it from a pawn store and they did not even know that it had a security code on it. So is their a way I can bypass they password or just reset the whole unit so that it does not have one. Also, where is the memory for this unit?
