hello...
the Dell XPS L502x ( Model P11F ) [ DAGM6CMB8D0 rev.D ..3 of lines output LVDS from PCH has short ohm(0 -70) than LCD displat turn ON but is white !!!
i decide to change LVDS ports to Lcd from EXT_LCD graphic Studio Discrete to No need it LVDS lines of PCH use...
according to ُSchematic ,I changed any resistor and... Config_0 and Config_1 EC...but:
1- EXT_LCD_PWM no voltage to enable pwm
2-EXT_LVDS_VDDEN no High to Enable LCD_vcc
and screen is turn off and fan is high Speed!!
Question:
I need to Use Discrete graphic nvidia EXT_LCD ports to use LCD and Cut the UMA mode.
and cut resistors UMA mode (Because some lines is short to 0 ohms -I suppose it was due to the connection of the metal to the outputs).
any friend Can help me...thanks.
Also :set D24 and D23 for LCD_Vcc And BL_PWM..
-move R398 to R394...
-Remove L43 1.8_run
-add R455 for dGPU_PWROK
-remove R672
-Add R219 and R232
Please guide me further..
