I have this display from Secant and the display backlight is dead.
The touch screen is working and I can still see the information if i shine a light on it or in bright daylight. I figured it's only the LED or whatever is lighting the back of the display.
This is the complete unit (back of display bottom left):

Am I right to think the two black wires are providing power to the backlight?
If it is, it's got to be AC voltage as the wires are coming out a the small transfo.
What should the voltage be? I'd like to feed the voltage directly to the display to rule out this part.
