Top 20 Pioneer AVH-P4000DVD Monitor Questions & Answers

Mine does the same thing, its not a wiring issue as I put a different Pioneer Head Unit in its place and the problem went away. I put it back and the problem returned

Press and HOLD MUTE. If you do install a camera, make sure it supports reversed image output, otherwise your images will appear backwards...

Reload software from Pioneers support web sight.

try changing the resolution of the album art pictures

Changing the dashboard can seem too costly.As you may need to replace the entire set.Try replacing it with the seller for a new one that suites your dash kitor sell it for a reasonable price at online shopping platforms.(Eg:ebay.com)

No. You can't play .iso files in any standalone DVD player.

I removed my Pioneeer AVH-P4000DVD from my Tacoma pickup to upgrade to an AVH-X2500BT and installed the AVH-P4000DVD in my mustang cobra and found myself suffering from a strange issue (that seems to have happened to a lot of you too). All of a sudden I had lost my audio on my USB and AUX inputs. I tore the net apart for a solution, pouted, drank, and started doing more and more research, and check instruction manuals. I eventually found the solution based of one lone comment someone had mentioned regarding ground and comparing the wiring diagrams for the two decks. I pulled the pioneer harness out of truck and compared it to the pioneer harness in my car and found an inconsistency. This may solve the issue that plagues you as well. Check the harness you are using. I was not able to find a pinout, but the 4 wires on one end of the harness for the AVH-P4000DVD should be +12V battery, +12V ignition, ground, and ground, (yellow, red, black, and black). If you have received the harness for a newer model of pioneer AVH it will still fit fine but one wire is out of place. The second ground wire you need has been replaced by a purple reverse gear sensor for the backup camera. Ground out the purple wire and it should solve your issue... It did for me. Good luck.

The noise is due to AC ripples in the power supply and so you will need to soften the power supply with the use of a isolated regulation or use of inductor/capacitor filters on the alternator circuit and the power supply to the system.In most systems there are filters but if the alternator has isssues- power regulator or rectifiers- then the noise can be evident.Please check with all the ground connecctions, check battery ground and the grounding of the set. You can try with adding a 0.5mfd/250V capacitor to the alternator circuit to be grounded.Finally check the power amp. ground, use a direct line from the battery with a fuse and avoid the source from the wiring harness.

are you using an amplifier or just the receiver to power the speakers? check the connections of the speakers, maybe they are just loose.

i have the manual for it .. i hope this helps -- ther are phone numbers to call Pioneer to get further information

The first things to check are th antenna connection at the radio and the cable at the antenna. If you have a poor connection, you may still get adequate FM through capacitive coupling, but the lower frequency AM signal would be severely degraded. If the connectors are heavily tarnished, polish them. If you have a telescoping antenna, make sure the sections fit snugly, but are not stuck due to dirt or corrosion (bad connection between sections).

If the antenna is good but you still have poor signal, the AM tuner is probably out of alignment. The alignment procedure is simple enough that it is a lab exercise for second-year electronics students, but it requires an oscilloscope and reference signal generator to get it right.

A real bunch of winners here!!!. Try turning on the ignition and pressing the reset button on the front of the unit with a ball point pen...

It sure sounds like a plug or wiring issue, aside from a fault with the unit, which is unlikely. Here is a Pioneer Plug for the unit on Ebay, at a reasonable price. I would advise trying it, and starting over. Here it is:

Like I first said, it's probably a wiring or plug issue. Good luck, thanks for using FixYa, and hope this helps!

mcdevito75 here, Monitor could be burned out, check all functions specially bright / dark, bring monitor to Staples, Best buy for testing.

Hi,

As you know, you can use this DVD AV Receiver with a rear view camera. And also it can be installed to switch automatically from the video to rear view image when the gear shift of the car is moved to Reverse position.

But it is important to use a camera which outputs mirror reversed images.
Otherwise the screen image may appear reversed. And this means that you will see the rear view reversed in the monitor. And that may cause accicent and injury.

To solve this problem, first check your rear camera whether it has the capability to output mirror reversed images.

If it is, then check the wire connections of the rear camera using the operation manual or ask a technician.

Also check the settings of camera polarity if it is set properly or not in the system menu when connecting the rear view camera.

You can download the operation manual (pdf file) by clicking here.

I hope this helps.

If you would like to vote for the answer, this will help the others to see the similar problems solved and also will be a satisfaction factor for me to continue helping you.

All the best.

mcdevito75 here, Monitor can be burned out, the picture portion of it. Exchage with a know good one or bring the monitor to any computer reair place, Staples, best buy and they will test it. Also double check all functions specially bright / darker on the monitor.

manual below.Download and it tells you all in there.

ERROR-19 Communication failure Perform one of the following operations. -Turn the ignition switch OFF and back ON. -Disconnect the USB portable audio player/ USB memory. -Change to a different source. Then, return to the USB portable audio player/USB memory.

You have take the wire that is suppose to go to the brake, and just run it to a constant ground.... BUT you have to put a toggle switch in the line to turn it on and off b/c after turning off the vehicle u will have to reset the switch u cant just hook it to a ground and leave it

1. disconnect all cables from the monitor except the power cable and turn it on if you see any test screen
the monitor is good if you see any thing .

2. then see if the cables are tightly fixed at both the ends i.e the monitor end and the computer end .
3. see if you can get some other monitor to test may be from a friend or a neighbour . the problem can be with the
computer also and very rearly sometimes with the cable
