              It may be a private labelled part for some OEM customer. Regardless, find a reliable (good reviews) vendor on AliExpress with Richtek parts.

              Ask them to source this '40=' Richtek device.

              They will carry it in Asia.

                          Trouble to identify part (Lunii screen) for replacement
                          by FreakyMex
                          Hello guys. I'm a complete noob in electronics. I'd like to repair my child Lunii's (a "story box"), basically an audio player that allows the childs to choose between several options the places, characters, objects of the story, and then play a story according to the choice of the child. There is a screen that display the selected option before each choice. The Lunii fell and the screen is now broken.
                          I'd like to repair it (probably just have to change the part, because the lunii still works perfectly fine) but I can't manage to identify the part/order it online. Do you have any...
