LG P990 Optimus display problem

if you call in-out can be done = try to replace lcd

First check:
Lcd Vcc 1.8 V at C826 (testpoint 1)
Lcd Vcc 2.8 V at C827 (testpoint 2)
Vbat (powerall) in pin lcd connector number 1
if the working voltage above still works well
rehot or replace lcd emi filter FL808 FL806-FL807-FL811-FL810-FL812 and FL813
see picture below ..?

dont forget to click thank
