@@VolodymyrIhor thank you for taking your time, I will help wherever I can, what is the history of the device? Alternatively, you can check out our WhatsApp line on the website, which would be easier for troubleshooting communication.
@@resetlab7142 I actually found shematic and cad for the version 820-02100 on some forums. However, there are some part on the CAD and schematic that is different from the LCD backlight circuit on my macbook mainboard, like some resistors and capacitors that exist the CAD do not exist on the lcd backlight circuit which is a bit confusing to me. I was hoping you could share schematic and CAD for the 820-02100-A main board. I will appreciate it very much 🙏
@@resetlab7142 the backlight is not working. I can see the apple logo very faint when I power it up. It still works just can't see any image once it fully powers up.
@@resetlab7142 When powering it on, I get a apple logo but very faint. When powered on it gets to the login screen (when plugged into a external display) and gets 12V to the backlight rail when on.
@@resetlab7142 Seems I maybe suffering from another problem that Apple refuse to take ownership of. Its a blurry screen. Not a backlight issue. Found a Apple thread.
no, while replacing my keyboard i broke a cable from the display connection. Its the thick one and i thing its the backlight. im still assembling my macbook maybe it will still work
Nice work! I updated to 15.0 and now my screen is black. I can only use my computer connected to an external display. (MacBook M1 Pro. 16-inch, 2021)

Hey, nice video. Where did you get the circuit schematic and CAD? Can I get a copy?
@@artinaj yes, I can give you a copy, how do you wish to receive it?
@@resetlab7142 can you please attach it on gdrive or sent it to my email?

Hey, I am getting 12V on my CP830 so I am getting power, but not the 16V what comes next in diagnosing that?

@@resetlab7142 Turns out I have a blurry screen issue that requires a whole new screen not just a backlight issue. :(
what's the software you are using for schematics?
