#1: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Tue Sep 20, 2011 12:18 pm ---- Hello everyone,
I've had a problem with the central display in my Peugeot (the one showing time and radio station etc.) for some time now. The problem is that it doesn't blank, as if turned off. However, it will display if I press on the screen...
This problem started when I previously had a radio problem, and as a result removed the plastic mounting around the display unit, and since I put the mounting back on this problem has been evident.
Like I say I'm a bit confused because if I press lightly on the screen it will display, as if it were working normally (but only while I have my finger pressed on it).
Any ideas?
Thanks
Chalky

#3: Re: Central Display Not Working Author: muzzy78, Location: LeicesterPosted: Tue Sep 20, 2011 12:25 pm ---- Had this problem a while back and it was a loose connection
#4: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Tue Sep 20, 2011 12:28 pm ---- Cheers for responses guys.
How did you go about fixing it Muzzy?
#5: Re: Central Display Not Working Author: kit325, Location: LondonPosted: Tue Sep 20, 2011 2:22 pm ---- need soldering on internal connection circuit, there's should be a guidance on HOW ＴＯ ｓｅｃｔｉｏｎ.

I'm going to have a crack at this this weekend. If the worse should happen (i.e. it goes tits up), would a spare display unit (plenty being sold on eBay) work as a replacement?
Cheers
#7: Re: Central Display Not Working Author: Lee, Location: EnglandPosted: Sun Oct 02, 2011 4:02 am ---- Yeah it should do
What sorta display is it?
#8: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Sun Oct 02, 2011 4:43 am ---- Hi Lee,
It's the 'PPT30'.
#9: Re: Central Display Not Working Author: Lee, Location: EnglandPosted: Sun Oct 02, 2011 4:46 am ---- That's just the connector on a non-plexed MFD
Is it the single or multi-line one?
#10: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Sun Oct 02, 2011 5:18 am ---- There is only one connection into the device, but multiple wires run into that connection (bundled together).
#11: Re: Central Display Not Working Author: kit325, Location: LondonPosted: Sun Oct 02, 2011 5:44 am ---- If it is the backlight problem, u will need to take it apart to do some soldering on the internal circuit board connection. Beware of the thin layer ribbon connection between the liquid display and the internal circuit board when u take apart the display or u will ending up with some dead pixel if u damage it. There's is a how to instuction in the forum u can use to fix it.
Just where about u in UK, if u in london i might able to give u a hand on this.
#12: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Sun Oct 02, 2011 5:46 am ---- Cheers Kit, in Sheffield mate.
Thanks for the advice.
#13: Re: Central Display Not Working Author: Lee, Location: EnglandPosted: Sun Oct 02, 2011 5:50 am ---- Nooo
This one...
Or this one....
#14: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Sun Oct 02, 2011 5:57 am ---- NR4 Lee. :).
Just taken display apart, the pin isn't broken...still attached to the circuit board.
Any ideas?
Seems strange though as I have the same issue as others where the display only shows if I press down on it.
#15: Re: Central Display Not Working Author: Lee, Location: EnglandPosted: Sun Oct 02, 2011 6:02 am ---- Mutli-line one then. Rare and expensive to find a decent second hand one.
Prone to failing.
If you need to press the screen, it sounds like the ribbon has come loose and you are having to press it to make the connection
#16: Re: Central Display Not Working Author: kit325, Location: LondonPosted: Sun Oct 02, 2011 6:06 am ---- When u said it only works when u press on, is the backlight or the display pixel? Because ribbon only for the displaying pixel, while backlight problem will be cause by the small pin connection.
On the small connection pin socket, check on the soldering, see if there's any small tiny crack on the soldering? Last edited by kit325 on Sun Oct 02, 2011 6:10 am; edited 1 time in total
#17: Re: Central Display Not Working Author: Chalky, Location: United KingdomPosted: Sun Oct 02, 2011 6:08 am ---- Yeah, like I say there's a few on eBay, in working condition, so will have to see if I can bid for one and get a bargain price!
...the piece on the circuit board isn't exactly solidly in place, there is some play. So I might have a crack at re-soldering it anyway and see if it makes a difference. If it still doesn't work I'll know it's the ribbon for sure.
Thanks for your help.

Your display illumination won't be the same as this as this one is a single line display but you can get the idea of what to check for. This is how I cured this one with a dead illumination display
]
First of all check you have the right type of bulbholders. The two at the top of the picture are different types, the one on the left makes contact on the opposite side of the board to where you insert, the one on the right makes contact on the same side, they look similar and they both fit so beware
With all bulbs out, use a multimeter set on resistance to find out which pin of the connector supplies each side of the bulb circuit board tracks (On this one it was the middle two pins). Ok insert one bulb, now with your multimeter still set on resistance and touching those two pins then you should see the resistance of the bulb, around 10-20ohms, if not then you have a poor contact. Clean up the CB tracks carefully using an eraser or electrical contact cleaner and try again, you may even need to bend the bulb holder contacts. Once that bulb is done and making a sure contact then take that one out and do the others the same. Now you know all bulbs are going to work if they have voltage across them

Problem resolved!
I just had to take out the set of the display wires and put it back in again
