From experience, I'd say it's a surface mount capacitor. You need to take it out of circuit & measure its value or else get a schematic & look up what ratings it is supposed to have. They are quite cheap to buy, so try getting a new one, as pilfered parts can be difficult to take the solder after removal. Alternatively, measure it using an in-circuit capacitance meter. It looks to be only used for filtering, so I don't imagine the exact value is critical. If I had to guess, I'd say it'd be around the 100nF mark. Such a part doesn't usually go faulty, so maybe it just needs a re-work?
