hello my friends
i have a board here that works fine on HDMI when lcd cable is not connected
when lcd cable is connected, lcd turns on but just black
another lcd and lcd cable checkd but no change
bios flashed but not helped
u72 was replacet in another repair shop but now LCDVDD_CONN is gooc

LID_SW#=3.3v
LEDVDD = 19V
+LCDVDD_CONN=3.3V
BKOFF#=0V
INVT_PWM= 0v
i see some activities on edid line

LVDS_A0 and LVDS_A0# resistance is 4.7k ohm
LVDS_A1 and LVDS_A1# resistance is 4.7k ohm
LVDS_A2 and LVDS_A2# have no connection at all
does it mean chip problem or should i check something else?
thanks

эти AM5000 такое гуано..... мог и отвалится, а мог и просто сдохнуть

Try to warm up combo cpu with hot air.

thanks but heating up doesn't make any change

as it had hdmi display i thought there is chance of repair for lvds
so there is no hope:(
