nikon n80 I purchased a sunpak 544 to go on my N80 and shot about a half of a roll of film and my camera quit working. (completely) I don't get any display of anything on the LCD screen. Nikon is telling me that the flash burned out the circuits and I can only use a nikon flash with nikon cameras. This is not a dedicated flash and I don't see how just using a hot shot adapter to fire the flash could ruin the camera. Any thoughts or help with this would be greatly appreciated. Thank you for your time

The speedlight stores, then releases a charge of several hundred volts to fire the flash. Older design non-dedicated flashes often do not have any circuitry to shield this high voltage fromt the camera. The voltage passes through the hotshoe when it completes the circuit that fires the flash. Back in the day, manual focus cameras had electronic metering systems completely separated from the flash trigger circuit. So the high voltage of the flash had no ill effects on the camera. Today's modern all electronic cameras have contacts that enable TTL metering with the flash. The camera is designed around a 6v to 12v power source, and is generally not capable of handling the high trigger voltages generated by these older flashes. The N80 user manual includes a warning about using non-Nikon, non-dedicated speedlights:
