Monitor Nightmare

I know there are a lot of people anxiously awaiting updates...

Waiting until tomorrow when I can talk to the tech support of a couple of paint stripping companies to see if they're safe on glass.

Stay tuned.
 
Looking at the picture you posted, it seems to me that there is no way it's coming off in one piece. Reading though your thread I can't determine if you plan on breaking it up first or if you are trying to get it off realativly intact. My approach would be to try and carefully break it apart and just pick the glass off in small pieces, then I would see what goo gone and a razor scraper could do to the remaining adheasive. Hopefully you can get it off and finish your restore! Good luck!
 
That's crazy! I've also done this using a razor but it was only around the edges.

Maybe one of these guys can spit acid on it for you but then again looking at your pics, not sure that would work either:

I can't believe the entire touchscreen is glued to the CRT glass face. That's just crazy. You would think that all that glue would reduce the image quality of the picture and even leave some bubbles behind the touchscreen. I have about eight 13" Wells Gardner CRT's from old metatouches and none of them have adhesive beyond the edge. I would just use a heat gun and slowly slide something behind each area that I heated up so it wouldn't stick back down to the glass. 30-40 minutes later and the screen is off. Your screen is a nightmare.

Could you just keep using a heat gun one small area at a time and just break those pieces off as you go? Good luck!

Same here!!

I am in the same boat!!! Ms. Pac cocktail that had a monitor replacement from a poker machine. Would have left it but it had a crack in the touch screen a few inches long from the corner.

This sucker is clear epoxied across the whole dang screen.

My only thought is to try and heat the whole thing as all the adhesive will need to be heated to come off at once.

Other thought is to start strategically cracking the touch screen in several places, soak in goof off or adhesive remover and hope for the best.

This is EXACTLY the only way to do it.

***USE EYE PROTECTION OR BETTER YET A FACE SHIELD***TINY GLASS FRAGMENTS WILL BE FLYING****
1. Get a metal scraper and heat up a corner of the glass to around 250F+
2. Pry and break the glass in a little section(it will decide itself the size) and slowly pry it away from the adhesive which will still be stuck to the CRT.
3. Spend about 2 hours doing this.

You will be left with this:

*THAT'S NOT GLASS, THAT'S HARDENED ADHESIVE*

Now you have to deal with the adhesive. I'm using Rustoleum Aircraft Remover. It's available at Autozone. I figured since it's safe on aluminum it would be less abrasive on glass. I haven't noticed any ill-effects on the CRT glass but use at your own risk.

1. Slather on the remover and let it sit for 30 min.
2. Use a plastic paint scraper to remove as much adhesive as possible.
3. Repeated the first 2 over and over and over and over and over and over and over and over.
4. When it gets thin enough, use acetone and a paper towel.
5. Vow to yourself to never take this on ever again.

I've never been to a sex shop but I imagine that's what the floor looks like.

Good on you. Glad to see it is coming along.
 
Heat will work

Well that sucked but got all the glass off.

Now to work on the adhesive/epoxy!!

That's just f'n crazy! I am in awe of your resolve to get this far. I'd be cruising the streets on garbage day looking for an old TV to tube swap and that would be in the dumpster. Keep the pics coming!
 
Heat is highly risky as it could damage the phosphor layer on the other side of the glass. It's so delicate that you just need to blow on it to ruin it.

Agreed. I could understand only if it was the last tube on earth.

Victory!!

So the process was to heat and worked off gently what I could followed by a 15min treatment of clean strip adhesive remover. I repeated that process probably 20 times but it worked great and the monitor still works great.

Had thought about LCD but the monitor worked just fine, just had a dang cracked touch screen glued on top of it.

So long story short, be aware that some touch screen monitors have the touch screen glued throughout the screen and not just the edges.

Bingo. The entire face is adhesive under the touchscreen. Here I thought the perimeter was a pain.

After breaking away some of the glass I found that sheet of adhesive which has now hardened into and extremely hard rubber-type material. On a hardness scale of 1-10 with glass being a 10, this stuff is easily a 9.

My next thought is to treat is as rubber and find something to dissolve it. This seems to be the ticket:

I am quite confident that paint stripper would make quick work of it as well as perhaps oven cleaner but I am not confident that they wouldn't etch the CRT glass. Open to thoughts...

By the way, this is for my Baby Pac-Man that I have been restoring for 4 years. This was the final piece of the puzzle. I expected to receive it and be finished. Here I am going into day 4 in getting the digitizer off. Heartbreaking.


Maybe this guy can help you
