[snip] If the circuit really is OU, then perhaps the signal source can be replaced with a small on board oscillator comprising a single HF transistor. It should draw it's power from the same connections as the LEDs, and it's output should be coupled to the wire that currently supplies the connection from the signal generator. It may initially need a battery connected across the power leads of the oscillator to get it going, but once running it should be possible to remove the battery.
