UV Lamp does not fire, but heating filament is working.
My DU-520 UV/Vis Spec UV lamp does not fire up, though the warm-up filement glows. I thought it might be that the UV lamp needed replacement. The new UV lamp had the same results. The startup diagnostics passed. No problem with the visible wavelengths and lamp. What would you suggest?

Thanks!
