The battery no longer held a charge well and became very sensitive to temperature extremes.
It went reasonably well. I'd browse the comment section of the guide as well. Sadly, the kit provided Phillips head screwdrivers did not fit the display connector screws. The screws were smaller and I did not have a smaller tool. The solution was to use the shipping box, weight it, rubber band the the box, slide the display beneath the band keeping it at a 90 degree angle, and then doing the work leaving the display connected.
Slow and steady, read the 'real world' comments for each procedure, watch a video, if over 40 get reading glasses or stronger prepped, and lots of light on a clean flat surface.
