Dvd Multimedia Problems

[torvil]

There are many threads on this topic, even a one from myself. However I wanted to inform everyone on a developement I've made with mine, whilst at the same time throw another question into the forum, along with any experiences people have with fitting after market products and reapir routes, so here goes...

MY VEHICLE 2004 FORD GALAXY GHIA 130 ELEGANCE

My factory fitted Visteon MB8000 stopped working over Christmas, losing power to the system, (no illumination, no power to screens, no sound, action from remote etc.

1. Fuses checked OK (both from fuse board & 5 amp on back of unit.

2. Power to "DVD Control Module" unit checked OK (red wire 12v main feed & white wire 12v from radio - only when switched on as normal procedure.

3. Power from DVD Control Module to DVD player OK (pin 4 red wire 12v)

4. Power from DVD Control Module to DVD player -FAULT (pin 7 PINK 0v) * I got all confused at this point and stated to make inquiries about getting the unit tested.

5. Booked the units in and posted them to AES (Visteon UK) aka www.fixmyradio.co.uk based in the west midlands near to Dudley. Although this was as good as useless as they sent the units back three weeks later complete with a note indicating "unable to test or repair", I did speak to a very helpful guy at Visteon UK who provided me with some very usefull info regarding diagnoses litrature.

6. Spoke to technician at Ford about my options. I wanted to know if or what was faulty. If the DVD Control Module was faulty happy days as I can replace this at £130, however with the a new DVD player at £909 I did not want to shell out the non negotiable £60 non refundable dianostic check for fear of it being inconclusive (like Visteon) and this would be halfway twds either a new Control Module or maybe an aftermarket system. I was rather cheeky by asking If I could order a new Control Unit and return it if wouldn't get my system back up & running again. Guess what the reply was!

6a. Took the units to a local guy who attempted to perform diagnoses whist at the same time inquiring about a hardwired aftermarket option - Result- £700 for a complete new system but £200 for a new aftermarket player inc labour to plumb this to my existing screens. This seemed a good option at £200 so I decided to put some scrutiny to this quote. BTW he returned my units stating he could not repair or diagnose problem.

6b. Another local and reputable installer took a look a the Galaxy who said to fit an aftermarket player to my screens would cause problems as all aftermarket players are a standard din size and would not fit into the normal slot (who wants a hole or a none working unit stuck in the rear of the center console?)

7. I went back to the drawing board and revisited point 4. Remember when I said I found a fault with pin 7 not providing power via the pink wire from the control module to the dvd player? Well I thought, the fault must be in the Control Module, so I found using my multi meter a redundant feed from the Control Module (on the same block a pin which doesnt feed a wire in the multi connector) and bridged it to the pink wire to fool it into thinking the pink wire was providing 12 volts-HET PRESTO!!!

8. I not only had power to the DVD player, illumination, disc spinning, screens powering, even sound, yes I was listening to the sound track via the headphones, but the pink wire now had power after removing the bridge, a bit like providing CPR to the Control Module jump started the initial fault "everybody stand back please paramedic coming through"!

9. So now I have a system which plays DVDs as sound, fast forwards/chapters etc, ejects and reloads discs, but only powers the screens to display blank illumination in a dark blue colour.

10. I now face the dillemma of weather to buy a Control Module (if only I could plug one that I knew worked ok in to the system to determine whether mine was faulty). My thoughts are it must be the Control Module as i dont think the dvd player would spin and play sound if the player was faulty, and I am doubtful of a loose connection to the screens as they are powering. Additonaly I cannot now control the system with remote control (batteries checked ok).

Can anyone share any experiences or knowledge with me please. I will update this post with any development or result.

Also, does anyone have an aftermarket unit hard wired into their Gal/Sharan/Alhambra, if so hows it fitted, does the player fit into the usual slot?

Hopefully this thread will assist people in the future, in the hope that we can keep kids entertained around the world, whilst travelling (ARE WE NEARLY THERE YET?)

Grr I did have a nice big reply ready for you but this forum sucks so I've had to retype the whole thing - instead, here's the highlights:

 

Controller should be powered at all times, receives an "on" signal from the dash radio in the form of 12V from the "power antenna" pin. Is the radio stock? Do you have 12V at that pin and more importantly is it still 12V when it arrives at the media controller? <10V isn't acceptable.

 

Controller checks all attached devices at start up and won't if anything is faulty. Wiring issues under the seat are common, have you checked the connectors here? The system will function with one screen detatched. Disconnect the wiring plug at the control module for each monitor in turn and try again to rule out a wiring/screen fault prohibiting operation.

 

The DVD player has phono outs on the back of it, most house TV's have a composite video in - a long cable between the two should rule out if the DVD player has stopped producing video (unlikely) similarly after that a shortish cable from the DVD player to the Aux in socket should confirm if the controllers accepting video from a different source.

 

Aftermarket systems very hard to wire into the factory system in a neat way - not least because you need a controller to talk to the screens.

 

From what you've described it sounds like the you've simply fooled the DVD player into firing up. The controller appears to still be in a sleep state hence you have no video and no IR as neither of these circuits are active at all times. I would concentrate my efforts here looking at the permanent 12V, the ground and the Signal On from the radio being ok and then check the screen wiring. It certainly sounds like the DVD player is ok and its a controller issue at the moment.

Thanks for the reply Mirez.

I have 2x12v into the system, one via the stock radio.

 

I have checked, and detached/ wiggled the wires under the seats, screens power down when disconnected/power up when reconnected.

 

The DVD plays as as I hear sound via the head phones.

 

I have managed to persuade my local dealer to order and supply a control module to try before I buy.

 

I will update with my progress.
