Z1 LCD Screen Replacement

New to the board.

I bought a Z1 as my second CPAP for traveling, and portions of the LCD screen have gone out.

It is out of warranty, and I couldn't seem to find a local CPAP repair shop that mentioned they repair Z1s.

I set it prior to the LCD going out, so it works fine for me when I travel. However, if I ever need to change my settings, i'm not sure i will be able to.

I found replacement replacement Z1 LCD screen online:

However, I have not been able to find any guide or video online that shows how to open up the Z1 and replace the LCD.

I'm pretty good at fixing things, esp if I can find a guide, website or video.

Just wondering if someone can help point me to a resource so i might be able to attempt a self-repair.

Thanks
