I've had a few problems with pressure points. All of which were solved by either
a) Removing screws on the rear-side of the front PCB
b) Removing the thin sticky plastic on the inside of the front faceplate (yes, this made a huge difference surprisingly!)
c) Removing the black rubber on the brown ribbon.

May be quite a late reply, but in regards to the v4 envy, it's meant to be installed vertically (with the wires sticking out the bottom, under the brown ribbon). They solder to either side of the capacitor. The tutorial you followed is old and out-dated!

Let me know if you need help. Unless you've already succeeded / given up ;P

That's what I figured, that's why I never complained about it. Not a big deal, and it's nothing I couldn't take care of in a few seconds.
I love your backlights... and I'm actually going to be ordering a few more this evening.

Nice!  I have a pocket I use every single day that I'll put one in!  Can't wait.

am doing, PCBs just aren't finished yet.  nearly, then a little work on them i need to do, then all done.

sorry

and installed in a pocket, they look pretty spot on to a light.  someone sent me pics, if i can find them i'll post them, but it looks sort of awesome tbh.  i don't keep pockets around and up to that point had only tested supplying power and not installed one.  its nice when people send in photos like that, hinthinthint

won't be too long on the el stuff

I don't think I've had any pressure problems with these yet...  But speaking of EL backlights, anybody gonna do those again or are they gone for good?  Wouldn't mind putting one in my GB Pocket just to make it look like a GB Light.

I can only think of a couple things that can cause that. Misaligned polarized film, or the LCD housing not being cut. Shouldn't be an issue, they don't lift the LCD higher than the foam that's removed, and they're also the thinnest gameboy backlights, excluding EL backlights.

Out of the 6 I've purchased 2 of them had the pressure points. Look at the photos of my Fallout Boy, and you'll see what I'm talking about.
I fixed it by removing the rubber strip at the base of the screen that keeps pressure on the ribbon strip.

I also have had this problem. Just right at the bottom I get a steady pressure point all along.

EDIT PIC:

I do have to say I was sort of blown away when I put this in an turned it on. It looks absolutely amazing!

There shouldn't be any pressure points, they're too thin to add any pressure on the LCD. Have you had this problem more than once?

Didn't even know you could still get the envy...

Yeah man. I love those panels. Easy install, nice even lighting, and the only problem I ever have with them is the pressure spots in the bottom corners of the screen.

Ok, maybe I'm wrong.  I'm thinking of the apeshit panels.  Those mount with the wires on the bottom...

Really? I'm pretty sure the envy mounted horizontally.

Also, rotate the panel.  The wires should be coming out the bottom, not the left side.
