It could be the regulator or motor, is this for the drivers door? The 406 windows are fairly easy to work at. The mirror glass is removed by pushing the mirror as far in to the top right, then looking under the mirror you will see the metal clip holding the glass to the motor, use a srewdriver to pop off the clip and then lift away the glass, but note that heated mirrors have wires attached to the glass.
The gameboy one, it looks like a similar type of display, ill try that technique, it must require a temperature controlled soldering iron. Ill have a go and see what happens. Thanks for your help
Thanks , I will try. By the way the window have to push servel times to get to the buttom , Do you think is the fult of motor ( inside the door )? Have you show how to depart the (ving mirror) glass that I can check for somehow the mirror didn't work as should be . Thanks you so much of your video .
The issue here is the LCD panel itself, not the connector strip or the circuit board. At 1:15 where you show the discoloured edge of the screen, this is where the parts of the screen have separated when it is meant to be a sealed unit. An LCD screen is made up of two glass panels with a liquid solution between them, in this case it looks like the edge of the panels has separated and allowed air in between the layers of glass which will cause this. I'm not sure why it happens so much on these panels but I can only think it is due to the temperatures inside a car, on a hot day the temperature inside a car can easily reach 70c then on cold days could go as low as -10 (in the UK where I'm from at least) and the constant hot and cold changes is the only reason I can think of for it happening. I've seen screens in other cars have similar issues in very hot temperatures, the clock in my mk1 Ford Focus used to go black and splodgy on hot days but looked perfectly normal on an average day. Unfortunately I don't think there's a fix for it, unless you can get a new LCD screen and somehow fix the connector ribbon onto the circuit board which is how I found this video, I wanted to see if it could be done but seeing the connector strip it needs a special machine to bond it to the circuit board.
+Robert Fitzgerald Thanks for the advice, it seems to be a frequently discussed issue on the forums, so far the only solution that seems to work is to get a good display then fit a small pc fan on it to maintain a cool temperature. Some other cars like the saab 9-3 and rover 75 have repair kits available, given this was a relatively rare optional extra there doesnt seem to be a big incentive for companies to develop a repair kit for this.
+peugeotCitroen2CV It's a shame as the screen is a nice upgrade and wish it was available on all 406's as standard. I'm still trying to find one myself and know several people with dodgy ones I was hoping to repair but a repair doesn't look hopeful after seeing these videos :(
+Robert Fitzgerald I dont know if someone who made these screens was able to reproduce them, or alternativley reprogram a 407 unit so it would work in the 406 (same screen sizes) then there would be an option. As a sat nav system it is useless, even by 2002 standards it was hopelessly out of date, in northern ireland it doesnt recgonise any roads and the last map update was in 2005. But the radio display and trip computer are useful
+peugeotCitroen2CV I'm not fussed about the sat nav, it was only text based I believe from reading about it but I just like the trip computer and how the information is displayed much nicer than the standard one. I've got the standard at the moment and without the standard stereo as well it's pretty useless and most of the screen (which was used for the stereo) is useless. I like how the sat nav screen made much better use of the available screen space
You can't these need a remote control But if you know someone with a remote control you can get one of them learning one 4 all remote controls to learn the commands and they can control the screen. Proper spare remotes do pop up on eBay every once in a while
Bummer, scrap yards it is then. Do you have anything on changing the steering rack on the 406 as mine seems to groan and squeak when turning and goes tight then slack??
The problem is they are all generally just as bad in scrapyards. Steering rack, no video specifically on that, but my clutch change video will get you reasonably close. Shows how to get the subframe off and at that point not much holds the rack still in place. Although I've done a video recently on changing the strut top bearings on a 607 (similar suspension) it can cause those symptoms you have just described and its a lot cheaper to replace strut top bearings than the rack.
If i can get a good working 2nd hand MFD from Ebay or a scrapyard, is it a simple matter of removing my old faulty screen MFD and just plugging in the replacement? Or will it need reprogramming etc?
ian heaver The difficulty is in finding a good 2nd hand screen, ive had a watch reminder set on ebay for 3 years and still havent seen a good one yet, i think all these screens are likely to have done this with age. However, as for reprogramming it needs an option changed on pp2000 from what i remember the steering wheel controls and cd changer will not function correctly unless reprogrammed.
Any attempt of repair is actually futile. Get 2006 and later displays, and install them, they don't suffer from these problems. Yes, they're expensive for some, but if you want perfect and readable display, that's the only way.
On the 2 button display that the 406 got there was actually an orange film that gave the screen its colour, that can be changed for a blue or green one. On this particular screen the solder mount diodes are given the colour.
I just bought one of these from my local scrappy for a fiver (worth a gamble at that price). Although it powered up and self reprogrammed the screen was terrible - my own, in my 2003 406 has just started to go, with a few lines missing. So I stripped it down as it is pretty much useless. My first mistake was to tear the ribbon, so I pulled the whole thing off. Doing this revealed quite a few places where adhesion was quite weak, in other places it was quite hard to pull off, so the suggestion that some sort of adhesive renewal makes sense. You could try heating the contacts where the ribbon is mated to the circuit board but I have a gut feeling that it is the glass to ribbon adhesion that is the issue. Pity I f*ck*ed it but will keep it to experiment with. I do like the trip computer function and still use the sat nav occasionally.
Ive tried heating the ribbon, but i think some sort of adhesive would be required to re stick it to the board. I have sent scrapyard screens to "experts" in the past to have them repaired to no avail.
Especially when £300 can buy a working 406 these days haha Stick the more basic Type B display back into the car, the sat nav itself is woeful, the only advantage to this display is that it can show more information. Just dont throw the old one away in case some time eventually a solution is discovered.
Are you sure its the same screen as this one and not the type b screen with a button at each side the type c screen as featured in this video uses solder mount diodes (i.e. small LEDs) to light up the screen they don't tend to fail. On the other hand the type b screen is prone to going dim on one half here is a video for that: Peugeot 406 MFD Bulb Replacement what you can look for on ebay is PCB bulbs.
actually its a peugeot 207 screen, don't know it's Type but its the exact 307 facelift screen. The bulbs are soldered to the board, but l believe l can re-solder new bulbs. l've found bulbs called "1210 PLCC-2" on ebay but not sure if its the same. Thanks for your interest
Quite late and probably you don't have the car anymore? 🤣 But, check the bulbs that illuminate the screen (they might be leds on the navigation version of MFDs)
I repair display's for all sort of cars and reheating the cable with a hot air gun / iron (WTF?) is NOT the thing to do. It's a fact the glue on the cable has come loose and will not stick anymore.... NEVER! Only solution is to get yourself a new cable and heat it to the board/display with the appropiate tools.
This never actually fixed the MFD But your mfd sounds like the one with the 2 buttons? If thats the case one of the bulbs at the back is blown and just needs to be replaced its quite a common enough issue
I tried to repair it too in my 407 sw. You can see it hier ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gWf4H7I86TU.html and hier ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Px4u2WBSCSE.html But i speak russian unfortunatly (i'm not russian, i'm ukrainian) . I'm thinking you can understand
Thanks for the video To fix the display have you put pressure on the ribbon going to the LCD? It seems like a good idea, ill need to see if it works on this 406 one.
I've just got a 407 with the same problem - despite it being a design flaw, I'm going to give both of these a go - if I can actually get the screen out! That cable is darned difficult to unplug!
