Question about Kenwood KVT-617DVD Car DVD Player

Intermittant power problem

I installed this unit in my 07 Pathfinder, and the head units lights flicker on and off. I've looked at the component boards on both the head unit and brain, and cannot find any "visual" deformities. I don't have a test set of any kind at this time, and was wondering if anyone would know of a possible solution that I may have overlooked. I have already checked connections and fuses, although I do not believe that these would cause a problem like this. Any ideas will be appreciated. Thanks.

I have a bv7320 head unit i am trying to install into my ford ranger. i have all of the wires matched up and im not getting any power to the unit. i have a amp powering all my speakers and a seperate one...

Since you did not mention the year of the vehicle, I cannot be sure of the power/ground connection. However, if you are sure of the connections, let us proceed. Check the constant 12 volt for power. Check the accessory power connection for 12 volts when the key is on. Check the ground connection for a good chassis ground. If you do not have power at these connections, check your fuses at the vehicle fuse box and at the stereo head unit itself (if one exists). If all power and ground connection are good and all fuses are good and, your unit still does not power on, check and make sure that the pins in the stereo harness are properly seated.
If all of these things check out as good then the issue is with the head unit.

Red light comes on but the unit wount turn on

The red light is associated with the memory (constant 12 volt power). You also need switched 12 volt power (power with key turned to accessory)for the unit to turn on. If you installed the system yourself, you are looking for 12 volts on the red wire of the Jensen unit. If power exists at the unit, check the fuse of the unit and the fuse of the vehcile.

Cant get sound in dvd mode only in radio mode

PS: Check if you car has remote wire or anterna wire.
Details below.

A relatively common problem is installing an amplifier with a factory head unit or other head unit without a remote turn on wire (or a burned out circuit). So the amplifier doesn't stay on 24 hours a day you need a way to turn it on and off remotely. Hence the term "remote turn on wire". Almost every aftermarket head unit has a remote turn on wire. Some manufacturers call it a power antenna wire. But regardless of the label all it does is output a positive 12 volts when the head unit is turned on. It should be noted that some head units have both a remote turn on wire and a power antenna wire. It's important to use the right wire for your amplifier and other electronic equipment. In the case of both remote and antenna wires the power antenna wire will only output 12 volts when the radio is on. If you were to connect your amplifier's remote terminal to the power antenna wire then you would only get output from the amplifier with the radio. When you switch to CD the amplifier would not work because the head unit turns off the power antenna wire when the radio is section is not active.
There are several ways to get your amplifier to turn on and off remotely even if your head unit does not have a remote turn on wire. The cheap and easy way is to run the amplifier's remote terminal off of a switched accessory wire. This is the wire that your head unit uses. It is only powered when the key is in the accessory or run position of the ignition switch. When you shut the car off the wire loses power and the head unit and amplifier will both turn off. Your amp will be on when your car is on and off when you car is off. If you don't want the amplifier to always be on when the car is on you could wire a simple switch inline with this new remote wire. Normally you would leave it on so that it turns on when the head unit is on. But if you wanted to turn the amplifier off you could flip the switch to off which would stop the flow of 12 volts to the amplifier's remote turn on terminal.

Pioneer avh-p7500 switch live

i dont know too much about these, but what i do know is, most of these units have a small 1 amp continuous blow glass fuse inside the unit, i would have a look to see if yours has it, and also look for any signs of over-heating on the PCB

Hideaway brain unit on my kenwood KVT-617 doesn't work

My KVT-617 display unit was stolen out of my dash, but they neglected to snag the items under the rear seat: the "brain" hideaway unit, the HD radio receiver, the 10 disc CD changer, the navigation unit, and the powered subwoofer.
Everything was replaced via the insurance except the sub because the new system was not compatible with the old components. Make me an offer on the items you want!

DVD head units have one extra wire in their wiring harnesses, compared to a standard CD head unit. On my Jensen, it's a peach-colored wire, and is the activation wire for the DVD feature. During the installation, the instructions call for this wire to be tapped into the emergency brake indicator light wire. The reason is this:

The e-brake indicator light is what is called a "ground complete" circuit. That means that the bulb always has power applied, but when you pull the brake, that puts a ground to the wire and completes the circuit, allowing it to illuminate. The head unit sees this ground, and activates the DVD player.

In my Jensen unit, I simply ran this wire to a ground (I used a screw near the fuse box), and I put a switch on the wire, so I could break the ground contact at will. Jensen calls for a procedure to activate DVD playback. In their instructions, they tell you to select DVD from the option menu, and when the "lawyer screen" comes up (the one warning you to park before you watch a movie), you release the e-brake for 3-5 seconds, and then reapply it. To simulate that with the switch I used, I leave the switch closed (activated), and select DVD. Then I flip the switch "off" for 3-5 seconds, and flip it back "on". This tricks the head unit into thinking I put the e-brake off for a few seconds and then put it back on, and the movie will start. Then I can drive away.

Basically, ground the wire that is used for DVD activation, and put a switch inline on it. Then you can break and reapply the ground in whatever manner is required by the manufacturer of your head unit. If there is no off/on sequence with yours, as there is with mine, simply ground the wire to a screw inside the dashboard and you're done.

Jensen VM9311/ UV7i wont turn on!!?

Yo, I've got the perfect solution to your problem. Pull out the head unit from your dash. Then, remove the wiring harness carefully from the unit. Now, push in the yellow power wire (even jiggle it a little) making sure it's tightly snug the small port of the wiring harness. Then, plug the harness back into the unit and try turning it on. I've found that the wires come lose easily on this unit. hit me back up at

Memory wont hold on AVIC-N2

Buy a cheap 12 volt tester pen from Radio Shack, and make sure your constant(yellow) always has power no matter  what position your ignition is and your accessory(red) only has power when the ignition is turned on. Some time those after market adapters are wrong(they are after market for a reason).

Rear view camera

The unit uses a wire from the back of the head unit to connect to the vehicle wire that sends voltage to your reverse lights. If this wire isn't connected or isn't connected correctly, the head unit can't tell when your vehicle goes into reverse. Most installers don't bother with that wire if the unit isn't being installed with a back-up camera.
