This display has the similar problem like another post on this forum for the same model of display-- backlight on, but LCD black. Following through that post lead me to take out the LCD panel and check it. Only it seems that HP changed LCD panel providers or Samsung the maker of the panel changed the driver circuit, because what I have with the Samsung LTM190EP01 panel is a different set of components. But anyway, I found that the one fuse on the driver board (F1) is blown. I didn't find any shorted capacitors, and between the terminals of the two voltage regulators (LD33 and LD18) there is some resistance ~2k on one, 500 on another.
I guess the best thing is to desolder them and test?
I noticed some marks inside identifying which wires go where, so I'm not the first person to have opened up the display it seems, and as I just purchased it for 10€ ("display is dim" the seller said), I don't want to put too much time in, but if there's an easy fix, that would be cool.
