Please check if there is a short in the high voltage circuit on the main pcb.
(probably a shorted high voltage driver-transitor)
You're primairy power supply will startup, detect a secundairy short, and shuts down again, then starts up again etc.. This could be the cause of the high pitching noise you hear!
Good luck,
