How was the de-vinigearing process?
Um, it's messy but straightforward. Some LCDs only have one film, usually on the top but a lot of the screens I've seen with the issue in IBMs have 2 layers - one on top and one sandwiched in the middle.
Most of them you can unpack and fold out the layers without having to desolder anything. I think with the PC110 I've done it by both simply unfolding and also desoldering one layer from another and then soldering it back in afterwards.
You can be really firm, I actually find the best tool to do the scraping is my own fingernail, though you can also get soft-ish plastic scrapers on amazon. My fingernail is tough enough to scratch off but not so as to scratch the glass. The glass is strong but you should use a thin cloth to do it on so that the other side doesn't scratch against the workspace you're leaning on.
I've tried lots of chemicals including 100% IPA but I've found that warm water is as good as anything.
The film - I've never actually found a perfect replacement and would love to hear anyone who has. I saw a guy in Japan who had found a perfect replacement but wasn't willing to share what it was. You can get various replacement films on ebay. I would try and get one that doesn't have one side sticky because it isn't necessary when you can tape it in place around the edges and then it's easily reversible. I paid less than £10 for the film.
There was another guy who had managed to modify a new TFT screen with a breakout board and then 3D printed a new front bezel, but his process was pretty handcrafted and repeating the process was looking at being expensive, time consuming and leaving the machine very much unoriginal...
