Hello all , Do you have any idea how to repair JE Dash Board. I've 2002 JE. We like the car! 2 days ago Dash Board started twinkling. I guess something should be wrong with connections? The easiest way is to buy new dasboard but I would like to save 1000€ if possible. Thanks and kind regards, Boris

Hello Lennart, I mean how to repair the dashboard itself. Regarding how to get to it, I have some notes/hints from the web. Kind regards , Boris

Hi again, Some years ago I've dismantled few instrumentation LCD displays for fun. There are some rubber connectors that are very sensitive. Maybe this is the case here as well, because from time to time my dash boards works perfect? (more time doesn't work though) Kind regards Boris

heh - I was just browsing through the workshop manuals for the dashboard, and came across this sencence: "It is strictly forbidden to repair this instrument panel. If a fault occurs, it must be replaced"
but of course, that applies to authorized garages, - not privateers. However, it might not be the best documented part then :/
Yes, I know the flimsy rubber-connectors you talk about (also from taking other LCD displays apart), - but normally such connection problems would give weird readings or dead segments - not causing everything to light up.
However, It could still be worth a try to take the thing apart and clean, - but I would be super careful, as there are probably a LOT of conncetions that must match up.

I'll step in too... this look like a display test mode. In your picture, Boris, I find it intersting to note that the parking lights indicator is on. This light is controlled by the CAN bus interface from the computer in the fuse box. So if that works, the CAN connection works too. So are the light indicators working or not? Otherwise I woudl check the CAN bus connection. I have never seen a diagram on the unit, and I doubt if any is available except if we can track down some electroncs engineer in the company that developed this part for Matra. Fortunately these CAN displays are quite often advertised used on eBay. Only problem buying a used one is that it stores the mileage of the car - the computer in the fuse box does to, but when the car starts, they negotiate the correct muleage - and picks the largest of the two. Fortunately a Renault garage can set the mileage for you to any number you want (!) I would not be afraid of taking the unit apart since it's not working anyway and I think the LCD is bonded to a seperate pcb in the unit. Here's the inside of it (source http://www.espace-freunde.de/users/mustafa/bilder-datenbank/je/karosse-innen/Winnie-DT/off-im-display.htm): - Anders

Dear Anders, I like your answer. It's not easy to pin pont someone who has worked on the projects especially on this particular part. Do you have some friends who worked for Matra? Do we know anyone who had problems with JE Dash Board? Take care , Boris
