Hello! 
I'm trying to fix a image flickering problem (from time to time) of a BenQ GL2580H monitor. Some times the image is perfect but most of the time when you turn the monitor on the image is flickering like the refresh rate is mismatched. It flicker even without connected source. After testing of the voltages unfortunately the main board lost power - power supply board still provides steady 18.04v (pcb markings says 19v) but that voltage is lost at U705 from the pictures. The component is labeled "YVAJF" but I cannot find anything in the internet to tell me what it is actually so I could replace it.
Could someone help me out?

Monitor: BenQ GL2580H

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
