I have a Esprimo Mobile V6515 notebook, which works generally normal, exept the fact, that there is no backlight of the display. I've already tested the display and the inverter, both are working properly. Now I've tried to measure the inputsignals of the inverter, but there is only 3 V voltage difference from 1 to the other 5 pins. The inverter is a TDK TBD510NR, has somebody a datasheet of this or knows which input the inverter should get? What can I try to get the notebook back working?
