There is an employee run arcade where I work that I am the de facto maintainer of, and the hardest part to keep up is the multiple 29" CRT displays. Specifically, their chassis (control boards in the pack) tend to need frequent repair.
Pulling the displays out of the cabs to work on them is also a huge pain. The size/weight has been mentioned here a few times; imagine having to pull a giant one out of an abdomen-height hole in a cab, and putting it back in without resting it on the plastic shell framing it.
