Hi all,
I have a dell S2715ht, it has an led strip backlight and has an odd problem, the led strip turns on for about a second before turning off. The monitor power led stays on and shining a flashlight into the screen reveals a good picture.
I was able to crack the monitor open and test the voltages going to the led strip, the led strip lighted momentary so I only got readings at that one given instant.
The led/lcd panel is an LG LM270WF7. I would be satisfied using an external power source to power the LED backlight, independent of the monitor; however I haven't been able to find any datasheets for the monitor or the panel. If anyone has experience with the wiring of LED backlights, help would be much appreciated.
Green (GND?)
Yellow (~15V)
Orange (19-20v)
Red (19-20v)
Brown (~15v)
Black (~15v)
