Hi guys, an asus vivobook with X580VD REv2 mainboard arrived in the laboratory and it turns on and I have video on the hdmi output but no on the internal monitor.
The problem happened after the internal monitor flex cut and shorted out. I changed monitor and gflat and setsso problem, I have nothing on video, I changed bios and same thing. From the diagram I checked and on U4501 I have 3v input but 0v output and on pin 3 I have about 0.14V. On the display connector on pins 26 27 28 I have 3V and on pins 36 37 38 I have 19v, what can I check?
