Maybe it's a long shot but in case anyone here has an LG flatscreen monitor that either won't turn on or randomly shuts off or goes to sleep, it can be fixed for about $10 in parts and a bit of your time.
Mine died so I Googled it and it turns out LG sold a LOT of monitors with bad capacitors on the power board. My model is the Flatron W2353V but this problem affects many different LG models. Google it to get details on your model and to see which capacitors you need. It's an easy fix for anyone with basic soldering skills. In fact, the hardest part is prying the monitor apart because it's not screwed together.
I'm no electronics wiz but figured it's either try this or toss the damn thing. I found this excellent write-up for my model and followed it. Note that you may need to click the small "Load Remaining Pictures" link at the bottom if the tutorial seems to end in midstream.
The electronics store didn't have the exact capacitors but what I learned is that there are 2 spec numbers on them - one followed by 'uf' and the other by 'V' (for voltage). Long story short, you need the 'uf' number to match and the voltage number to be at least the same, or higher - NOT lower. So for example, I needed 3 caps that were 1000uf/16V. The store had 1000uf/25V, so that worked. The other was 470uf/35V and they had that one.
You should be able to find details on your exact model through Google along with as much detail as you want on any aspect of this. My needs were simple - what do I replace, and how? ;-)
Again, maybe it's unlikely anyone here has this problem but figured I would post this just in case. My monitor is like new for $10 in parts and about an hour of my time.
