Full Version: Disaster: How _not_ to peel the AG off of an LCD

This was the first LiquidVideo LCD that I'd taken apart, and broken by chipping the upper right corner. While experimenting with removeing the AG I decided to peel off the polarizing layers as well, as I'd been unable to completely remove the AG from the front polarizer. But getting the polarizers off of the glass was much easier.

Then I noticed that a hairline fracture had spread through the glass from that first little nick in the corner. I knew this was the death knell for this LCD but figured I may as well finish what I'd started and see what the LCD looked like sans AG and polarizers.

Then with a loud CRACK the glass splintered apart, some of it remaining stuck to the polarizer.

C'est la vie. ^_^

Wow. That is a real disaster. You must have tried to pry the lcd off from the front metal frame to have broken the corner and caused the lcd fracture. I noticed the LiquidVideo frame bottom has 4 or 5 places with metal bent inward to keep the backlight, lcd and frame together. I just simply used a cutting plier and cut one end off, and bent them out. The backlight can then be lifted from this side quite easily. I supposed we are dealing with glass here and have to be very gentle.
Anyway, you have done two lcds. This info is probably not useful to you. Would you suggest removing the AG from the LiquidVideo lcd based on what you have tried?

Why did you try to remove the polarizers? I thought the lcd required the polarizers to work? Or were you thinking of replacing them for less tinted ones?

I hear its pretty difficult to replace the polarizer evenly and nicely on top of your LCD. Looks like that small crack spread like the plague in a pre-school...sorry for the sick metaphor.

I found the AG -very- difficult to remove. The glue it's stuck down with is not water soluable nor is the AG itself, so ragging had zero effect on it. So.. it might be a good idea to try polishing first, see if that's effective enough on it's own.

I didn't intend to remove the polarizers to begin with, but the AG was -very- difficult to remove. I'd managed to remove about 90% of it, peeling it off in difficult to grasp strips, using an x-acto knife to get under the lip of it. I'd also lifted up the edge of the front polarizer, by accident.. it came up easier than the AG since it was stuck to the glass. So I figured I'd just peel of all of the polarizers and replace them as well. Which is when the above disaster occoured. *urf*

Has anyone successfully removed the AG from a Liquid Video panel yet?

I have the LVideo 1512 and the AG would not budge after a 12 hr soak..
I then managed to get both ag and polar off together and have since replaced the polar with a high contrast one from polarization.com. Works a treat..

But as for removing ag on this panel..Ive heard of no successful strips as yet...sad.gif

how about using a hair dryer to strip it with or a regular stripping gun. It may just get gooey and pull off easier.

I've read elsewhere on the forums that LCDs are tempurature sensitive, which is why there's so much emphasis on cooling them in a finished projector.
