Hi all. I want to share my success story. I got a monitor with the same symptoms - totally dead. I ordered new parts for IC401 and IC402. When I tried to replace IC401, it was stuck on the board. Even 450 temperature did not help to remove it. So I used a polisher machine to remove it (be careful, you can easily break the board). Next, I soldered new parts. After I'd done, I checked the voltage and got 1,8v but no 1,2v. I opened the datasheet for IC401, and 1,2v should be on 3rd pin. I double-checked the microscope and discovered that the leg did not connect to the board. I soldered twice leg...
