Great work here

I feel sorry that I destroyed 2 of my DS3s when they exhibited some sign of malfunction which could have been easily fixed by some cleaning. One I opened & never reassembled until parts got lost and in second case I knew the film was an issue and chose to clean it with nail polish remover. All contact point on film just got dissolved
I replaced the film and it worked okay went in storage, pulled it out a few days back and its dead. Might need a nudge to film/contact point but not feeling like doing it all over again. Have a 3rd working controller so PS3 again went back in storage.
