lcd and inverter checked no problem.
I suspect the problem exists on the bios. because I've experienced the same thing on a similar motherboard that is HP 14-v201TX DAY11AMB6E0 REV.E
Flash bios of the same type (HP 14-v201TX) problem solved. previously flash bios of different types with the same kodeboard (eg HP 15-p248TX DAY11AMB6E0 REV.E) laptop screen actually even become dark. that is my experience
I hope you can understand
thanks a lot
