Hi there.
I got this pretty nice monitor a couple of years ago and it worked fine until the day it didn't. No power surges, just shut down while I was using it with my computer, and while attached to a APC SmartUPS. After some research it turns out that this LG 31MU97 does tend to die after a year and half of use (just read massive number of reports of such on Amazon). One company in US actually developed a service specifically for this model to fix the issue, and, it seems, it all revolves around replacing just one part on the mainboard - EEPROM IC205 which regulates power input.

They sell the chip itself or the service to apparently replace it on the board.
Being outside the US, I can't really avail myself to their service but I found an alternate solution on the internet which seems to have worked but I can't find any logic behind it and decided to ask people in the know whether or not that solution is worth trying. It is posted in a blog here:

Basically it involves shorting pins of the same EEPROM chip to coax it into working again. This seems to be rather dangerous and yet it the only feasible solution available to me. I would appreciate however if someone could explain the logic behind this and alleviate some of my concerns with this operation.
