20 Most Recent Panasonic CQ-DFX403U CD Player Questions & Answers

look for areset botton if it dosent have one by a cd cleaner if after that its the same replace the radio

There are two pre-outs for amplifiers but there are no AUX inputs to play MP3 players.

The heat is normal due to the large output IC's Panasonic uses. You need to get a "Laser Lens Cleaner" one that uses fluid. You can find them at just about any retail store these days for 15-20. Run it thru a couple times and hope that's the magic bullet to fix the issue, otherwise it needs service at a cost of 100-150 on average. If the cleaner does the trick, make it a habbit of cleaning your player every 3mos or 3000 mi. It truly is the best preventative maintanance on any CD/DVD/PC etc.! Hope this helps

This is the link to your units pdf manual. It also covers a 7 series model which does have "Aux in" Your unit does not. You do have the capability to add a cd changer via the link on the back of the deck but it is Not an auxillary input. Now, it is correct that you could use a FM modulator running thru the tuner on 87.1 or 89.1. I think the confusion on this unit was a quick glance at the manual. It does have an "audio in" but it is specific to the panasonic disc changer and triggered thru the changer din cord. which is why you see no "Aux" on the display nor hear any audio. If you look at page 5 in the pdf version of the manual it states that the 403 does "Not" have aux in. The manual reads tricky on the other pages, sounding and looking like they are detailing the 403 when in fact the example is the 783. At the moment I can't think of a "good fix" for this pickle. I'll noodle it thru and if I can get you a solid way to make this do what you wish without lots of signal loss I'll post another comment. Hope this helps explain what's happened.

If it has never worked, chances are the illumination lead was not hooked up. If it just went out, pull the unit and check the fuse behind it (if it has one) and check the vehicles fuses as well. Repair is not cost effective if it needs to be serviced by the manufacturer and Panasonic builds great product but has slow service. If your not mechanically inclined, most car audio shops charge 20-30 to check it out for you. Hope this helps.

Hi Rembo,

 

From reading the manual on your deck, you do not have an Auxilliary input for something like a MP3 player.  now if you want to hear your MP3 player on the Deck , you will need to get you a Fm transmitter with auxilliary input.  I think they have those at Best Buy.  Thats where you hook your MP3 head phone output to the AUXilliary input on the FM transmitter.  You would have to tune your Tuner on the deck to the frequency of the Transmitter.  Coolest thing to do with your Deck is to download all the songs you love in MP3 format on your computer, and burn about 150 to 250 of those songs on one CDR. Then play that in your deck.

The rca plugs can short out. Or one of the comparator that is for audio selection. Might can get away with just replacing them

Hi Greg, I'd say you have a bad audio output IC, generally this will take out the fusable resistor that feeds the output stage, you should be able to find a part number on the IC, do a pin out and check between B+ and ground pins with it in circuit and see if you see a short. I don't know if you can find a service manual for it but hopefully you wouldn't need one

Question edited for clarity and typos. The first thing with CD Ejection issues is to try a CD Cleaning Disc. It has brushes to clean the laser optics. They always fail on the low power tracking laser. When it fails self test, it ejects. also First unplug power for at least an hour, then press and hold the power/on button while plugging back in, and keep holding for another 60 seconds . Here is the Service Manual https://www.manualslib.com/manual/683358/Panasonic-Sa-Ak87.html https://www.google.com/search?q=panasonic+sa-ak87+cd+keeps+ejecting+disc ....

I'm sorry, but wiring diagrams for specific car audio systems are not readily available to the public. These diagrams are usually confidential and used by authorized repair technicians only. If you need assistance with the wiring of your Panasonic CQ-C1100U car audio system, I would recommend reaching out to the manufacturer or an authorized repair service for support. They should be able to provide you with the information and guidance you need to properly install and wire your system. It's important to follow the manufacturer's instructions and any relevant safety guidelines to avoid damage to the system or potential harm to yourself or others.

It sounds like your SA AK 133 5 CD changer has some issues. The AM radio band not turning on could be due to a faulty antenna, a problem with the power supply, or a software issue. To resolve this issue, you should check the antenna first and make sure it is connected properly. If the antenna is connected properly and the issue persists, you may need to check the power supply or contact the manufacturer for assistance. The issue with the CD not ejecting could be due to a faulty drive motor or a faulty eject mechanism. To resolve this issue, you should check the drive motor and the eject mechanism and replace them if needed. The issue with the tapes not working could be due to a faulty cassette player mechanism. To resolve this issue, you should replace the cassette player mechanism.

This indicates that the CD player is ready to receive a signal from a Bluetooth device. To connect your device, you will need to enable the Bluetooth setting on your device and then select the "PANASONIC" device from the list of available Bluetooth devices. Once the connection is established, the source button should stop flashing and the audio from your device should play through the car audio system.

Hi, Check that the equalizer settings are what you want when you are playing audio using a BT connection. The user manual states that the settings are memorized for each source i.e. tuner, BT and CD, which I assume means that it can be set differently for each input type to suit what you want
