Buy an Icarus Excel screen?? (Rebranded Onyx Boox M92)

[nataliebeck]

Somehow my Icarus Excel/M92 display broke and I really want to replace it!! Does anyone know how I can have it replaced or have a device that has an intact screen that they are willing to sell for parts? Please please let me know and thanks in advance if you have any information!

I think you can send it to Booxtor (ereader-store.de) to screen replacement. I suppose other Onyx M92 distributors (as Artatech ) will do it too.
And you could ask to Icarus too
But screen replacement it's quite expensive.

And Booxtor said that there is some setup to do, this depends of the screen :

Thanks for the feedback! I'm really hoping to find a way to do it myself, if at all possible, but I certainly won't put my ereader at risk.

if you are so eager to do it yourself, please follow disassembling instructions here first. https://www.mobileread.com/forums/sho...d.php?t=178058

Take care of FFC (flexible flat cable) which connects control button to the mainboard - it is easy to break those contacts - you will have to solder them afterwards.
Be also carefull by detaching of the screen from inductive panel - it is attached by doublesided adhesive tape. Please dont hurt yourself - brocken screen could have got dangerously sharp edges .

As soon as you are able to detach screen - half of the job is done.
Look at the voltage label of the screen. It should be a number like -1.37 (a value between -1,10 and -1,60). When you place an order for a replacement screen, please ask the seller for a screen with at least similar value.
If you have luck you will get a screen from a batch with same waveform version as used in your device. In other case you will experience some troubles with contrast and correct presentation of grey levels. In this case you should ask the seller for a waveform file and must be able to get to console of the device (i.e. using special developers USB cable) to be able to install it. Please ask your distributor for root password (console) of your device.

Please don't bend FFC of the screen - it could damage conductors in the FFC. Hard to repair issue. Just fix it carefully with adhesive tape.

You can also try to install a recovery update. Afterwards in main menu you will get a voltage adjustment tool. Just set your voltage value to the same value like on label of your new screen (using joystik). This tool will disappear after setting have been done from main menu.


PS: I still suggest you let our specialist do this repair - we have know-how and can do it fast.

I don't quite understand this part

So will i have to solder the FFC cable contacts anyway or only if i break them?
I just need to know if i can replace the screen simply attaching and deattaching the cable/tapes (as in samsung phone for example that i have fixed) with my bare hands?

Also apart from physically replacing the screen are there any things that i have to do before the reader can work properly (motherboard adjustments, bios, etc)? Or is it just replace ang go ?

Best regards.
