I have a gateway laptop that the inverter board went out on it had a part number of YNV-W10 for the heck of it I replaced it with one from a long gone HP with a part number of YNV-W15 and it came on I shut it off right away didn’t want to chance problems the only difference I can see between the 2 boards is the Gateway one has a larger chip here are some pages that show the chips the first page is for the original board
