I knew the XL4005 needed replacing. I replaced it twice with an IC from a variable power supplies that I use in my workshop.Each time the NLBA did not work,
I then ordered XL4005E1 via Ebay. It arrived quite quickly from China and fixed the NLBA

Thanks for your help

hello, im reading this about the u5 chip, where should i order it the programed one. ?

The U5 chip is flashed with firmware and it is secured. A new blank U5 chip will not work, only the chip shipped by the manufacturer (already flashed with the firmware) will work.
