Re: please help friends fix this bios dell 5490 la-F401p, lost LVDS signal DISP_ON MI
thank you sir, I have checked lvds
+BL_PWR_SRC ok 13,v
+LCDVDD ok 3,3v
DISP_ON 0v this signal comes directly from the chipset there is no pull up resistor, and the resistance is fine, meaning you can be sure that the chipset has a problem
