One of my remote controls died recently. I'm trying to find the problem component on the board and I believe this is it. However I'm not sure what this component type is called, and more importantly, where to find another one. Help identifying it would be much appreciated!

    Possibly a 4 MHz ceramic resonator, considering the "X1" designator. – Peter Bennett Oct 22 at 17:19

    If you don't know what the component is, how do you know it is operating incorrectly? – Digital Trauma Oct 22 at 19:35

From the designator (X1) that would be a crystal or oscillator of some kind.

From the shape and given that it has three pins, I'd say it is a ceramic resonator being used in an oscillator.

From the marking, most likely 4MHz.

    Oddly enough the device to the left looks like a 32KHz crystal, probably to keep a low power mode going on the remote. Crystals can get damaged if they're mechanically abused, they're not as tough as ceramic resonators. – isdi Oct 22 at 17:23

    Having three pins suggests that this ceramic resonator includes the two capacitors used in a Pierce oscillator. Usually the high-value resistor (1Megohm) is not included....some 2-pin microcontroller oscillators have this resistor inside the chip, while others don't. – glen_geek Oct 22 at 17:32
