I was on 498 (redeye) SEA-BOS that got to BOS this morning. From the entire time I got on until the time I got off the screen was staticky and not working. Pressed every button, it wouldn't even turn off. It looked like most other people's screens were working. There was also some problem with a computer and an engine which is why we sat on the ground for 30 minutes or so before taxiing (and we got told about it after 20 minutes of waiting.)

Just not a good experience overall for a first time flyer on jetBlue. I did get to sleep a bit though. I didn't want to bother the crew or anyone else about why it wasn't working and I did kind of want to sleep.
