Servicing some older X series.. After power up, there is an audible beep/alarm that triggers about every 2 seconds.. sometimes the flash tube will fire in sync with the beep. Installed new flash tube etc. caps all look good inside.. anyone with any ideas on what may need "servicing"? Thanks Timmyz

I would suggest re-seating and trying a different AC source. If the problem persists, the flash will need to come in for diagnosis and repair.
