Question about Panasonic CQ-VD7001U Car DVD Player

1 Answer

No Sound I bought the unit used to replace my existing Sony headunit. It did not come with an installation manual. There are no speaker level outputs only RCAs. I thought it was going to be a simple swap, but I can't get any sound. The amps are fine, the line is fine. Is there something I am missing?

Re: No Sound

Go to your local car audio stor and buy a rca to speeker wire converter or buy an equalizer and use your speekers

Im not sure which plugs I should plug my RCA cables that come from my amp to the reciever. I dont know if its the "back RCA output" or the "Front RCA output" or the "subwoofer...

First of all get yourself a Y-LINK cable. (single male RCA on one side/ double female RCA on the other side) Connect the Y-LINK to your head unit sub woofer output with the stereo RCA that leads to the sub woofer amplifier. Now you are connected to the correct output. I do not know what head unit you had connected before to base your comparison, however there is a output voltage difference from one head unit to another, (1.2V, 2V, 2.5V, 4V, 5V) and that is what determines where the gain on the amplifier should be set to. Always match the headunit output voltage with the amplifier gain control to be the same. It is not uncommon for some entry level units to have a single sub woofer output. dreamsystems

Hi my name is james im having trouble with my audio coming out the speakers what should i do

1. Do you have power to the unit. I assume yes.
2. Ensure the fader and balance is set to neutral to ensure you have output going to all the speakers.
3. Ensure the speakers are connected.
4. Ensure the speakers are not out of phase, if they are they will cancel each other out, and sound muted
5. Always test new model head units with a cd. not fm radio. Using fm radio on some head units will mute the sound if the station is not coming in clear enough.
6. Set your volume up a little, like on 15 or 20 (using the digital 40 level radios) (halfway in plain language)
7. Ensure the mute isnt on
8. If running through and amplifer, ensure the power, ground, remote, gain and phase are all correct.
9. Ensure rca input is going into the correct place on the amp
10. Ensure speaker output is actually connected to speakers.
hope this helps

On my jensen vm9311ts its shows my dvd playing but no sound. aame thing with my ipod. its says its playing, but no sound. what wrong?

I'm guessing you're not using you're head unit to power your speakers/subs you're probably using a separate amp so your problem is not likely to have anything to do with your jensen headunit. first just make sure amp is turning on, if it's not check all your power wires(pwr, grd, remote) if it is turning on check your rca cables. it's a dvd player so theres more rca's in the back of the unit, it can be confusing so it'd be easy to mix somthin up... if everything checks out ok and you still can't get any sound take it to wherever you had it installed and have them look at it till they figure out what's wrong

Kenwood dnx7100 in protect mode


Your receiver is detecting a problem in the speaker wiring and is going into protection mode. If the receiver shuts off due to volume level, this can be caused by a poor connection, damaged speaker, insufficient gauge wire, or connecting multiple speakers to one speaker output. The connections at the receiver and speaker should be clean with the ends of the wire twisted tightly, preventing any strands from missing the terminal. Connecting two sets of wires together to add distance should be done with terminals and insulated to prevent the wires from touching each other. If using thin wire, replace completely with heavier gauge wire; do not add to the existing length. Be careful not to push the speaker wires in too far, this will cause the speaker terminals to grip the insulation and not the conductor. The speakers being used must have an impedance within the range listed next to the receiver’s speaker outputs, normally between 6? - 16?. The impedance of your speaker should be listed behind the speaker itself.

If problems continue, disconnect the speaker wires from behind the receiver and power the receiver on. The receiver will shut off quickly if there is an internal short and would need to be serviced if this happens. If it stays on, try connecting the speakers one at a time. Replace any speaker that causes the receiver to shut off.

Have one wire for audio sub out, but two input ports to amp

This one Wire should be for the +. Try connecting the + to the Head Unit and - to a Common Ground. At the Worst, You will Blow the Amp Fuse if not Correct. The Lead from the Head Unit is Only an Off and On from the Ignition. Please Rate My Response! Thanks!

No audio

Your output chip probably fried. SAME DAY AUDIO SERVICES offer to fix them on Ebay for about $100. He is very reliable. You can also add a small amp and run your speaker, it would sound lot better and cost about $100. Goodluck.

Car DVD player will only play sound through wireless headphones, not through speakers

We have a GMC Envoy which also does not allow us to play the sound from the dvd player through the car's speakers. Although we purchased the vehicle new with the dvd player already installed, it was installed by the dealer, making it after-market. I assume those that were installed in the factory work differently. Maybe this is the case with your's as well. Good luck!!

I dont get any sound

Many vehicles have factory amplifiers that must be activated or bypassed when installing a replacement head unit. If the factory amplifier isn't integrated or bypassed, you won't hear sound from the factory speaker locations. Another possibility is that you have a shorted or pinched speaker wire or terminal. A short at any speaker will shut down the head unit's internal amp, killing the sound to all the speakers. The RCA outputs wouldn't be affected, so the subwoofer keeps playing.
