HELP NEEDED E85 cluster display issue

[Walker]

Hi guys, having an issue here.
When the ignition is turned on the cluster display working as shown in the first pic but within 5-10 seconds it goes blank (second pic)
Cycle the ignition and same again, the screen obviously works but no clue why it’s doing that.
Any ideas?? Thanks in advance

No one know anything?

Likely the lcd display is failing or the contacts are corroded

Fairly easy fix as the display can be replaced and doesn’t need coding

I think you've got a fault no-one's seen before. I would say that it's a backlight fault - if you wind the instrument brightness up full is it apparent that the backlight is going off?

The backlight seems to be on, it’s just the numbers/info is going off

Thank you, I’ll pull the clocks out later and strip them down, see if I can see anything

Stuart, can the display be replaced separately then, without having to swap the whole unit and swap over the chip?

Yes

When you take the cluster apart the lcd screen is removable as it’s held in place with clips

Same applies to the auto gear change lcd

Seems it needs a refresh

The final OBC retrofit thread

I have read a little here and there on this OBC turn signal stalk, and I figured I would give it a go. Apparently if your E46 did not come with the BC button on your turn stalk which allows you to view outside temp, MPG, etc. you can install the turn stalk WITH a button and the car will begin...

...You have to explain to the dealer what you did and want you wish to accomplish. I told them about the button and how it just needs a reflash through the MODIC. I hadn't found any good updated instructions so I wanted them to tell me exactly how they did it if they activated it. My service advisor was really interested in what I was trying to do, and the mechanics were as well. I told them it shouldn't take more than 5 minutes to do from what I saw...

What is MODIC?

Reflash. Auto correct wins again

Arhh haha no worry’s, where would I get that done? Is that a specialist job?

Sorry I don’t agree that is flash issue at all

My bad. Replied to wrong thread. Sorry

I took the lcd out and there was no corrosion etc that I could see, it’s strange as ever time I turn the ignition on it works for 5 seconds same time everytime, it leaning towards the lcd not been broke and it being a different issue but I’m not sure

 

[bigwinn]

Worst you can do is try another lcd

It may have a loose solder which is affected by heat

 

[bigwinn]

I have approx 10 spares if you need one to try

The timed cutout makes me think of a failing electrolytic capacitor if there are any on the board.

Thank you for the offer, there are clusters on eBay for about £20 so I’ll just buy one of them as my lenses has scratches anyway. If I plug the new cluster in to check if it works will it cause any issues with the Milage?
I had a Megane that I changed the clocks on and the new ones had a higher Milage and it altered the cars milage immediately
