checked in external display ok but internal white display coming
checked with new lcd with cable but same issue
then checked in lvds conector found 18v ok
but lcd_vdd not present pin 7,9,11
which is coming from q7 transitor of pin 1
q7 pin 3 have 3.3vs and pin1 have no volage which is called lcdvdd voltage
lcd_vdd voltage is missing
change the q7 transitor and checked display working fine
