I guess I will post this here as well, as I work on my guide. It's not finished, and this is the second iteration. If you want to see the original stuff, and some fighting between me and bacteria you can go to this thread:

but now for the guide, so far:

Alright; I will redo the first part of the guide as well because I feel like it. I need to redo the trimming work anyway.
Let's start with chapter 2,3 (I'll rework the pinout chapter tomorrow or somethin' I don't know, it's getting dark here so I can't take pictures without flash anymore)
Chapter 1: Pinouts
(this ended up being a bit confusing. I'll redo it later in anything but paint)
Chapter 2: before we start
Got your screen ready? Ok. Good.
I strongly recommend protecting the LCD with something (I used the plastic from the original screen) - you'll be looking at the back of the board a lot and always taking it off first gets old soon. You don't want your precious screen to get scratched to Heck, so cut out a square from a plastic bag and temporarily tape it to the screen.
Now, while you trim the board, it is suggested to ALWAYS test it after and before each step, so you will need some kind of signal that you can send to the screen. You can also use your playstation until you trim off the bottom, for convenience. Either way, make sure to always sufficiently test it. If it doesn't work, make sure you followed everything right and that you didn't short anything out and didn't cut any traces and didn't damage any components. If you did, relocate the traces and try to replace the components.
Chapter 2: The right side
This is the easiest part, you need to reconnect two wires. One is ground, the other one is some trace that leads to a component at the bottom of the screen, on the front, but you can just connect it to 7.5V. Confused? Don't worry, I'll explain it better later on.
Did you test your screen? Do it.
Remove the LCD. (Remove the power first - never do anything with the power still on.)
Make sure to close the brown thingie again. BE GENTLE! It breaks very easily. Disconnect the plug with the pink & white wire on the top as well.
So how much can we cut?
Yellow: Easy mode. Pretty much impossible to screw up
Orange: Medium. Still pretty easy, but be careful not to cut too close, you'll just end up destroying something.
Red: Still entirely possible with just two relocations. It's unnecssary to cut off this much, though. I wouldn't do it unless you really need to for some reason. Of course you can cut anywhere between the lines as well. I'd recommend not cutting open the hole for the LCD ribbon, though. Leave that intact if possible at all.
See these components connected to the silver pads? They don't do flax. You'll probably destroy them during the trim job, and it doesn't matter one bit.
Let's do the orange one
Lookin' good. But Now we need to reconnect some stuff.
See this thing at the upper end of the trace we just cut through? We need to reconnect it.
If you want to be a goodie two shoes, AND aren't going to trim the bottom, then you can connect it here:
That's where the trace lead to, before we slaughtered it. BUT, it's much easier and will work fine to just connect it to 7.5V (a good point for this is the first lead of either 7805 on the board):
That it? Nope. We split the grounds. We need to reconnect them before the screen will work again. If you look below the right side of the transformer, you will see a solder pad for a missing component:
Connect this solder pad to the ground on the other side - Namely down here near the LCD ribbon hole:
And that's it! Your LCD should be working again, regardless of yellow, orange or red path.
Did someone say red path?
Chapter 3: The left side
Not much trimming to do here, but at least it requires no relocation. This is the big part sticking out.
This should all be pretty self-explanatory. I recommend going with orange, i.e. medium here.
Don't forget to test the screen!
Chapter 5: The top
If you're not going to LED-mod the screen
Again, we have easy & advanced mode. Easy mode being pretty much impossible to screw up, and advanced mode being not that hard either, but requires care not to cut through anything.
Yellow: Easy
Orange: Medium
Red: if you need it.
My recommendation here is yellow or orange. Anything else is overkill. You'll probably only need yellow, if at all.
Two worlds, one motherboard.
