I'm not an engineer, but my monitor stopped working yesterday (it just wouldn't display anything but still gets power) so I figured I'd like to take it apart and see what went wrong. At the very least I'd get to see what the inside of a monitor looks like :). Anyway, I took it apart, and also read around about my issue and it seems the capacitors have gone bad, at least some of them. However, I also noticed some white elastic stuff all over the board. Some of them are sticking two capacitors together and to the board, but I also see some from where power socket connects to the board.
My question is, what is the white stuff? Should I replace all capacitors that have white stuff around it, and should I also replace the power socket part? Or should I just replace the bulging capacitors and leave it at that?
