Car dvd player ir transmitter wont work - Alpine Car Audio & Video

are you listening via FM transmitter function?

if so, make sure that you do either.

1) when watching the same DVD on both screens, disable the FM transmit on one DVD.
2) when watching separate DVDs on each screen, make sure that the frequencies are separate by as big a gap as you can make.

I had this problem and it was due to both screens transmitting on the same FM frequency and interfering with each other.

I also found that the lower FM frequencies stopped my GPS from working!

After altering the FM transmit settings (FM-TX) button on remote, it was all good.

Hello... I am sorry to hear you are having problems. I am unsure if you bought this as a package deal with the headphones or purchased the headphones separately. If you purchased them separately, they may not be compatable. Headphones come in different frequencies. The reason for this is if you had 2 different dvd players and 1 kid was watching Spongebob and the other kid was watching Hannah Montana, they would not interfere with each other as far as sound. Some dvd players will allow you to change the output frequency of the IR (infrared) transmitter built into the dvd player. This feature would be in the menu section of your dvd player. Make sure the headphones are on properly, because if they are backwards, they may not read, because IR frequencies are "line of sight" meaning the receiver (headphones) has to see the transmitter (dvd player). You will see a tinted window that has 3 or 4 bulbs. That will be your transmitter. Make sure you have good batteries in the headphones and that you have them turned on. If you have power and have checked the IR frequency, and they were purchased aftermarket, then you may need a different set that receives the correct frequency. If this is a package deal and you have checked the batteries and they power up properly, you may have a bad IR transmitter inside the dvd player. With the info you provided I can only speculate at this point, but this gets you on a start. Let me know if I can help more! Good luck with your venture!!

I had rca remote that did not recieve ir signals but rf signals instead. Check online with rca or in owners manual for what type of signal factory remote sends. The dvd player I had was 5 dvd and that was the case. Dish might have an option like direct tv where you can program rf signals as well. Call dish network support or look online

To setup your IR Blaster (transmitter), hold down the channel up and down button at the same time on you the unit for more than 5 second until the unit says bye and 12:00 flashes, then power on unit and the setup screen will come on your TV.

Do you have the manual? Here is the link

First thing to do is check to make sure that the batteries are properly charged.

Second, make sure that you have a clear line-of-site to the IR transmitter. Infrared (IR) works the same way that your TVs remote control works - if the signal is blocked, then you will not hear any sound.

Third, make sure that you are in the rear seat of the vehicle when listening to the sound. The IR transmitter only transmits to the rear seat, so you will not hear any sound if you are sitting in the front seats. This is a common problem that i see.

Lastly, make sure that the heapdhones you purchased are compatible with your 2006 2007 2008 2009 or 2010 Toyota Sienna. Remember that some older models require RF headphones, not IR headphones. I checked http://www.audiovideo2go.com for compatibility before I purchased my headphones. They have a useful listing of all the headphones and models of vehicles they are compatible with.

if the headsets work the fm transmitter may already be working. unless they are using an ir signal. you can test this by blocking the the ir or (infrared) led's on the lcd and the dvd player , if the headsets still work than its probably being sent via fm signal. turn your head unit on to fm andstart at 87.1mhz and work your way up to 89.9mhz in .1mhz intervals fm transmiters are usualy some where in that frequency.hope that helps

Firstly, make sure your DVD have built-in IR wireless module so that your headphone can receive the audio signal from your DVD player.

Second, it should be clear which frequency transmitted from your DVD player. Generally speaking, there are two frequency of IR transmitter.One is 2.3MHz/2.8MHz. another is 3.2MHz/3.87MHz. Only emission frequency same as receiver can receive the audio signal.
