I am completely new to the electronics game, so please excuse any layman's terms.
I'm trying to repair an LG IPS234V monitor that has recently started glitching. Once any video input is attached, but only after about 30-60s, the screen will flash up bright lines every 3s.
I've replaced faulty capacitors in a plasma TV and older LCD screen and guessed it might be the same thing, so I opened up the monitor and can hear similar clicking noises to those previous cases.
The only thing is, the part of the board where I can hear the clicking has none of the bigger electrolytic capacitors I'm familiar with.
There is a disc shaped component, labelled with an overlined 100, that has a small hole in it's side and looks as though it may have leaked - is this just a smaller version of the electrolytic capacitors? If not, what type of component is it?
Everywhere I've read has said to use a ESR meter to test a capacitor in board, but is there any way to test it with a bog standard multimeter?
