I was hoping to remove my a/g from my LCD, however my LCD is framed in its metal frame from the monitor, and that frame is attached to the wood frame by silicone. biggest I was wondering since I can not see the edge of the a/g film if I could cut the outline of the LCD (drawn in red on the picture) and remove it that way, or would there be too much of a risk in damaging the lower layers. My main concern is if I use the rag method that the soaking process would seep into the lower layers causing them to separate as well. Any advice would be great. Click to view attachment

I went through the same dilemma. I just grit my teeth and peeled away at the silicone until I could finally remove the wood frame and metal frame. Good luck in whatever you do.

Yeah the wood frame is not a problem, but the metal one is attached to the LCD with JB Weld, a steel epoxy,the stuff is basically steel in a tube. Big mistake on my part, but live an learn I guess.

I think if I soak the screen first then cut a little on one corner I should be able to start peeling without cutting into the lower layers in any other location. Then hopefully just cut the a/g at the edges once its peaked back.

I think i will try it anyway. Ill post results good or bad.

As much of a pain in the behind it will be, your best bet would be to remove it from the frames. If you leave it in the frames, the frames themselves and possibly the monitor would get water in some odd places due to cohesion. the easiest way to stop that process is to remove it. You might have to pick at some silicon for a while, but you will increase your chances of success by quite a bit.

Another thing-- what LCD do you have? Is there a high success rate for the model? If the AG on your monitor was anything like mine (Samsung 512N), I URGE you to either figure out how to remove the monitor from the frame and attempt the procedure properly, or forgo AG removal completely. Seriously, if I had tried to cut straight down in to the AG (I basically did when I tried to peel it up with a razor blade) I would have ended up doing more damage than good.

Basically, if your monitor's AG has a reputation of being rediculously easy to work with, then I'll let you decide. But if that stuff doesn't come off effortlessly, I wouldn't suggest doing what you're talking about.

An alternative to completley removing the AG and TAC layer would be to use polish.

Here is a picture of a sample polarizer that I polished using Mother's Mag and Aluminium polish.
It shows the reflection of a window. The top part is polished and you can see a clear reflection.

And if you don't like the results you can always try the full strip later.

Nice work using the Mothers, prime. How long or how many applications did it take you to get it that gleamy? Bet it looks good on projection

liemaz: I was able to remove the a/g on a panel that was still in it's housing. Of course being very careful not to push alot of the chemical underneath the housing while scraping was the important part. Some DIY'rs at the sister thread 'Ll projector lumens theory Ii' were able to do their a/g strip while the panel was also in it's frame. Just letting you know.

Thanks for the replys, i braved ahead with my plan afterwards and it worked. The a/g came off in three large strips. I did however loos a tiny square of polarizer near the edge, about the size of 4x5 pixels. Luckly its not in a area thats important.

I tested the screen with a flash light and found no dead areas of the screen, so now all i have left to do is remove any remaning stickly spots on the screen.

Sim,
It was only a sample so I didn't need to be very careful so it polished up quite well, it was very easy to polish. After doing this I tried it on half of my SGI LCD but I was a bit more careful so it hasn't polished up as well. I have also tried it on my other LCDs but they seem to be much more resistant to the polish. Personally, I like the polish approach as it seems to give some improvement but leaves the TAC which protects the polarizer.

Hi prime
I also have a SGI panel and have been wondering if polishing would show any noticeable improvements. Does it?
Barry

Hi Barry,
It's only noticeable if you are looking for it. I've done half of mine and it is not as reflective as the sample, needs a bit more polishing. I don't really notice the difference when watching a movie but the desktop is slightly crisper, the screen door is a bit sharper.

It's a really good way to remove those dirty fingerprints

Thanks for the info prime.
I may try a small area on my panel this week. I've got some stuff, X-scratch or D-scratch? that is for polishing CDs and DVDs. We had a small accident with some car cleaner once and this stuff really did some magic. What happened is we left some cleaner on the clear plastic that is over the gauges and when the car got hot the cleaner actually etched and pitted the clear plastic. It is crystal clear now and it has been two years since we had the problem.
Barry

We I just finnished trying the D-Skratch and it didn't do too much at all. The panel is a little clearer but when I look at the surface under magnification it looks like very very fine orange peel.
Prime did you ever strip your SGI panel?

I used Mothers on my panel which improved it greatly but it had a grayish haze. I polished it with d-skratch ( or any other compound used to polish the scratches out of CDs or DVDs) after and the haze went away. In the picture you can just see the difference. left side of arrow Mothers, right side d-skratch. This really improved the colors/contrast of the projected image.
