Backlight Switch Lite 41v output (no 17v)

Hello everyone. I’ve had a problem with the backlight on the Switch Lite - not 17 volts but outputting 41V. The inductor gets very hot.
I changed the bga 9 pin chip with a new one. Still 41V.
Why so much? It needed 17V. Thank you

Where do you measure the 41v? at inductor?
