| Rear entertainment monitors |
|
Hello to all
Please forgive me for joining the forum and then immediately asking a technical question but I suspect i am not the first and won't be the last.
Firstly I have 5 different Land Rovers but my every day drive is a D4 Discovery in Zanzibar Gold (or orange as the DVLA insist on calling it).
I am a retired robotics engineer but can I make the rear monitors stay on for my grand kids to watch? NO!!
I will explain what appears to happen and ask IS IT ME!!
When I insert the DVD and turn them on, all is good. As soon as the vehicle starts to move obviously the front monitor goes blank but so do the rear monitors and then they turn them selves off.
Is this a setting, a fault or normal.
Thanks you in advance and hopeful anticipation.

Hello and welcome!
Your electrical knowledge will far exceed mine but sometimes the basics get overlooked?
If you've retrofitted then however you've connected them up it sounds to me like the picture cut off when the vehicle moves is kicking in as it supposed to on the front screen but it is kicking in and killing all signal to the rears.
There is a software fix that keeps the front screen live when moving although I am sure that you realise the inherent dangers in that... Google is your friend if you want that install.
Maybe worth trying? Jim

Thank you for your prompt reply, I don't believe it was retro fitted but it was all in when I purchased the vehicle, there was one former keeper.
I don't really want to mess with the software, maybe that is my past employment making me a little shy of installing third party software as I suspect it would be.
I just want to know if there is a setting that I can change to sort it out.
I have tried to look at it but it is difficult on my own as my arms and legs are too short to drive it from the back seat

Ah, sorry. I misunderstood your initial message.
FIrst point, you have read the manual on the in car entertainment? Or have Googled for it?
ISTR from my last D4 that had factory fit RSE that it could be set as per the front monitor screen.
There should be no need to retro fit anything but just work out the different settings. Jim

Thanks Jim
I have read the book but can't find the answer.
I have not googled it as I find you get 10 different replies of which 9 are a load of fiction but you don't know which one is fact so I thought I would ask the people who know.

If they do, they're here.
Must admit, I had a RSE entertainment D4 and I could have sworn there was a setting for that.
Someone will be along soon with an answer I am sure... Jim

I would have to check, but I’m sure my landmark has a limo mode and the rears stay on, or at least the tv can be operated via the remote control.

There is a limo mode but it appears to do it if that is selected or not.

Don’t use just select:
Rear seat entertainment, then choose both LH and RH screen sources to TV (or dvd) etc. Then you should have what’s needed on the rear screens.
Regards

So, the plot thickens.
Is there a PIR in the rear monitors as it appear that if I set a DVD playing and sit in the drivers seat the rear monitors go off, but if I sit in the rear seat (vehicle not moving but engine running) the rear monitors stay on.
If so it appears that my 18 month old grandson in his car seat it not big enough a heat source for the PIR to see.
Also if I sit in the driving seat and wave my hand in front of the rear monitor it comes back on.
Somebody put me out of my misery

Rather than a heat sensor, it is probably a weight sensor to detect presence in back seats. A car seat sometimes straddles and misses the sensor due to the shape of the base. A few big bags of sugar on one of the other seats? Restrained of course ...

In a spirit of wanting to be helpful and sheer curiosity I have tried to recreate what happens with your RSE in my 2014 D4.... and I cannot.
The rear screens playing a DVD keep laying whether static or on the move, whether someone is sat on the rear seats or not.
I think what you might want to try is finding a friendly similar D4 and going through the settings in tandem with them.
Do you have a remote for the rear screens? You should do. Just possible that maybe playing up and interfering but I cannot really see how. Worth looking at though.
Happy to be a tandem D4 if you are around Oxford and we can make timings work...

OK Jim the car is a Landmark, is RSE the same thing?
Yes I do have a remote but I don't think it is that as it does it with the remote in the front but it won't control the monitors unless it is in the back.
In response to DaveJLBI if it was a seat pressure issue why do they come back on when I wave my hand in front of the monitor even if there is nobody in the back.
Still a mystery to me.

I’m a bit late to this but you’re over thinking it. The IR sensor on the screen is for the remote, that’s it.
The screen coming on when you wave your hand is coincidence. What I suspect is, a short in the passenger seat wiring which kills the whole RSE, it won’t blow a fuse, it just disables it until it resets. What I would do is go under the front left seat and disconnect the 2 plugs underneath at the rear (grey and blue I think). Then see if the drivers side headrest screen works as it should. If it does, you have your answer. I had the same issues as you describe only I found it to be the drivers side seat wiring. A brace in the back bolster had rubbed through the insulation and shorted. Sometimes it worked for a few minutes, other times not at all. I didn’t even realise that it was shorting as I got in and out of the car. 012MY RRS 5.0 Supercharged Autobiography (Current)
