Hi,
The ESC if working properly , will provide 4.8 volts to the receiver via the plug that connects to the throttle port of the receiver. There is no need for a receiver battery . Make sure the ESC is plugged into the proper receiver port and make sure the polarity is correct. You typically won't short out a receiver by plugging in an ESC plug backwards but the receiver will not get power.
If the suspect crystal is of the same frequency and band as the working receivers crystal and it will not work in the other receiver then that crystal is dead.

List the radio ,receiver make and model , the band and frequency, and the make of the ESC you have.
