That is indeed the part. Thanks MR37. For some reason, I was unable to find it just by googling. We're leaving on vacation in a few days and won't be back for two weeks, so sadly it'll have to wait until next year. I'm just going to try and get it out of my mind for a while, otherwise for the entire two weeks it'll be eating away at me. I will definitely order the part from bluestar if I don't find one in the 15" Trinitron (which, like you said, seems unlikely, but I will check anyway).
EDIT: I have to order at least two, bringing the total price to $10, and then the shipping is $9 (!). For something that could easily be mailed in an envelope?! There's no way my parents will let me buy this, they'll me to toss the monitor
Better start searching locally, or call bluestar and see if they can take a money order so my parents won't find out how much I paid.
