The transistor that drives the coil in the Borg ship is almost certainly toast.
The front of the manual has the “Q” number of the transistor. I bet it’s nice and toasty.
It’s time to own a digital multimeter and learn how to test parts.
Or, you can send the board to me for repair. I can bulletproof it for you. Send the MPU too for NVRAM installation and get rid of batteries forever.
LMK if I can help. My feedback is easy to find here on PinSide
