Bosch Purion dead pixels

[Ilisescu Cosmin]

Hello community.

I have a problem with the display of my electric bike, a Haibike Sduro Hardnine 4.0 2019.

The display is a Bosch Purion, and as you can see from the pictures, after I turn it off, a few pixels remain lit on my display. After I turn it on, they turn off, but they are no longer visible on the display.

I mention that I changed the batteries of the display, took them out, left the display without batteries in it and without the bicycle battery overnight, and still did not solve the problem.

Has anyone else experienced this? Any solution is welcome.

Thank you!

That usually happens, when the rubber contact of the LCD is not connecting clean to the board.
But they are cheap used, should not be more than 30€

You mean the contact between the display rubber and the display board, right?

Do you have any idea if I can disassemble the display or should I look for an electrician?

And can you tell me what it looks like or a link to that product?

Failed pixels are not repairable. If the display comes on, and all data shows up, it is not a contact issue.

That is totally not worth it. They are dirt cheap used.
If you were in the US, I would just send it for the shipping cost.

Thanks for your interest, but unfortunately I'm not from the US. Where could I find the necessary things to be able to solve the problem?

Most likely the water got in somewhere around a joint of the screen, around a seal... I'll try to see if something can be done before I replace it with another one

Are you just guessing, or do you know about how panels actually work? According to Google, there are 2 conditions to a black spot. One is a dead pixel and the other is a stuck pixel. A dead pixel is absolutely not fixable. Here's a source in the UK. https://www.e-bikeshop.co.uk/products/bosch-purion-performance-display

I took the display to someone to disassemble it and indeed, as wildtrak said, it is the rubber that makes contact with the display board. Do you have any idea where I could find a kit with these rubbers?

In another Purion.

Why the resistance to buy a replacement display? If you found an old used display, you'll get the same dried out seal. You could have a pattern shop make a mold to cast the replacement rubber if you still insist on not replacing the display

I don't want to buy a new display at the moment because I don't see the point of paying 100$ just for a contact rubber. I'm going to use it like this until it dies completely and only then will I buy a new one.

It is not the seal. Just read my first reply what was confirmed by Cosmin. If you know how LCDs work, you know what the issue is.
And the rubber seal actually does not dry out. Maybe after 30 years.

I didn't find traces of water in the display, so it's not the seal, it's the rubber that makes contact with the screen, exactly as you said above. Thanks to both of you for the advice.
