There are two types of resonators, ceramic with 3 leads and L/C with two leads.
The last one can also have three leads, but the thirt one is a mecanical lead.
This resonator you can also find into remote controls for radio and tv, the yellow or blue cubic part.

The yellow part is also a resonator.



BTW, you can place two 15pF capacitors with the old resonator and you have fix the problem.....just try
