Repair LG 60PB6650-UA not starting or starting with no image due to failed YSUS EBR77185601

Just fixed three YSUS boards EBR77185601 all with the exact same failure symptom and I think I narrowed it down to the essentials that need to be replaced for it to not fail when you try it again.

EBR77185601 is used in LG 60PB6650-UA, LG 60PB5600-UA, LG 60PB6600-UA and possibly others.
My experience is summarized in the below video:

The board failed twice on me until I had it all figured.
Actually there were three failures, but it turned out the last one was not the YSUS itself even though it sounded and looked a lot like it, only when I took it down it was all good and upon long and close inspection I found a noise filter cap busted on the top buffer board:

The video mentions that, but doesn't include the picture, which I took before finishing the work and ensuring everything worked fine at which point I made the video.

LG 31MU97-B main board exchange and repair services now available

A few years ago I came across the 31MU97-B 4K monitor.

It was love at first sight, partially because it was beautiful and probably just as much because I got it for about $20 (it was $800+ new) total because its display was coming in and out and it was rendered unusable.

Turned out it had  a tiny detachment  on one of the display tabs and I found the location and was able to actually fix it...somewhat.

I stuck a piece of hard paper between the LCD and the front bezel - it was even hidden from plain view - and that caused the detached tab to make contact well enough to a point where the TV would work for say 30 or more minutes.

Over time, however, probably due to the paper going thinner, it started failing more and more again and it got to the point where I pressed a little too hard one day and it cracked.

I had already gotten used to it by then and just bough a refurbished one, which I use to date and still like.

The parts of the old I listed on eBay and this is how I learned about someone wanting to get the main board.

I don't remember the details, but he eventually ended up sending their board to Coppell TV Repair LLC and we took dab at it.

Since then we've repaired a few other dead main boards from different LG 31MU97-B monitors and we've seen two different issues develop on those; I am sure there are more that will show over time and I can't be certain we'll be able to identify or fix all of them, but for the time being we are glad to offer exchange and repair services:

1) Exchange service for LG 31MU97-B main board (or rather buy a good working board and please please return yours without being tampered so you can get credit for it):

Note that sooner or later someone would either buy a board and not return theirs or return it and we won't be able to fix it; which means the exchange may not always be available.
