This product is for Nintendo Switch owners whose LCD ribbon cable connector is broken. It's designed to replace the faulty connector, which often happens when the flip lock breaks, causing the LCD ribbon to lose connection to the mainboard and resulting in no screen display. By replacing this part, you can fix such issues and get your Switch's screen working again. Note that it requires detailed soldering skills and tools like a tri-wing & philips #00 screwdriver (not included).
