Question about Pioneer AVH-P7480DVD Car DVD Player

1 Answer

Wont power up!

I bought a used dvd player from a friend who claimed it worked prior. When I got it it was missing parts. I had to buy the 16-pin power/speaker harness for the brain unit and the antenna extension whire. I have everything wired propery (checked with test light). The in-dash unit has power to it (security light flashes) but the unit will not power up when ign is turned on. What cables are need to be connected to the units?? I have the power harness on the DVD player, and the power harness on the brain as well as the IP-BUS cable. is it possible I need another cable that is missing when I got the unit?? is an RGB cable needed or is that just for and add-on?? I have the manual but it doesn't list the "Parts Lists" Thanks!! Matt

    It was missing the RGB cable. Now it powers up but it doesn't play DVD's or CD's. the disks load and spin but you can not change the SOURCE from TUNER to DVD or CD

    When you hit the SOURCE button it should change from TUNER to DVD to CD etc. Only the TUNER fucntion is working, can't get cd or dvd to play. I can only get the radio to play. I bought the unit from a friend who said it worked so I am assuming i have a setting and or cable wrong??

    when I connect the AVM output to AUX video input i can make the DVD play and I get a picture but no sound. Going from AVM out on the main unit, to AVM in on the brain is the way is supposed to be hooked up and that doesn't wok....

I have a tevion car radio cd player model 2413 but dont have the 16 pin harness plug where can i get one thank you

You could contact Tevion support forum here
or go to ebay and type in 16 pin car audio as your search, you may find what you are looking for there. I haven't seen one, is it a standard iso type?
Surely if it is Tevion specific there should have been one with the radio?

I bought a Bose power supply. I can plug it into the system but not into mains. It is missing a cable like a figure 8 on its side?

This is a relatively standard 120V cord that you are missing.
Commonly found plugged into DVD players and VCRs. If you have an old DVD player or VCR, see if you can't snag the power cord from it, and use it to connect the Inverter to the outlet.
Or buy one.

Missing part

Charger does't connect to DVD player.

Connects to battery. Built your own, Radio Shack, female to male jack, power supply from anything handy or spend $2 at thrift shop, $2 multimeter (Harbor Freight, Cheapo), junk variable resistor (pot).

7.4--8 V adjust. Or, get fixed value resistor dependent on PS voltage.

Charge anything,

And power supply for DVD house current.

We had thunder storms my tv 65613 has a green blinking light wont star

Good Day,mikeybecerra; TV wont come on mb try these 6 items, please pay attention to the blinking light (it's a code) : 1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067001 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). LED stops blinking after 70 seconds of plug in but will not power on. 5. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 6. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001. Good Luck, big IRISH.
