Just wanted to post another successful clean. I followed VBs documentation and it was pretty easy.
I did a few things different I will note. For the adjustment screws, I took a silver sharpie and marked each one. This way I could get them back to the exact position. Also even though noted to only loosen the right side one, the left one was kinda glued or stuck, so I gave it a little twist and then used a screwdriver to pop it loose.
For the actual lens cleaning, I just used a micro fiber cloth I had left over from a film protector that you put on phones. Or maybe it was for an ipod, but either way that doesn't matter. I didn't use any lens solution either, just wiped it with the cloth. It was a little tough at first, but it came off after a couple firm wipes. Then just kept rubbing in a circular motion with a clean part of the cloth until it was nice and smooth.
I also cleaned all the fans etc. I just removed them and used compressed air instead of trying to do it with a queue tip while in place.
I video taped everything I did, that way if I needed to go back and review to see something I could. If I was better at video editing, I would make it nice and pretty and post it, but I'm not. VBs pictures I think are enough to go on though.
My picture is nice and bright. I also replaced my bulb, so that comes in to play, but I definitely had crap on the lens.
I think the only thing I would have done differently is go into the ISF and check the overscan first. Maybe have taken a picture or video so I had that to compare to what it looked like after it was all put back together. I don't think mine was dead on to begin with, so when I got it all back together I noticed it was a little crooked. I must have messed with it for hours before I finally just said it is close enough.
Oh and if you do mess with the rotation screws, you can't just adjust one without moving the opposite screw in or out. So as you tighten say the right, you would need to loosen the left just as many turns. If not, you will just start bending those metal arms out. Learned that the hard way
Thanks to all that have helped build this thread.
