A few months ago, I made a topic about the missing/faded pixels on my P1 - images are here: http://imgur.com/a/rarUd
I was told to open it up, and clean some areas with a q-tip/cotton bud and some alcohol, & I have now finally gotten round to open it up! Although I'm now unsure about which areas need to be 'checked' or 'cleaned'.
Here are some pictures of the surgery in progress: http://imgur.com/a/yHNRq
I can provide more pictures if needed!
Thank you in advance
