It is pretty common with the older generations of DMD/MFU “flash” systems like that the Pershing is using to either burn out the bulb or “flash” system or both. My M51 and M4 also use the older generation and both “flash” systems are no longer functional. It would be worth it for you to try a new flashbulb & wire set just to rule out if it is the bulb or “flash” system.
