Is your Philips Lumea IPL 9000 not flashing even though the ready light is on? In this step-by-step repair guide, I show you how to fix the common "no flash" defect by replacing the blown IGB50N65S5 transistor.

Many Philips Lumea Prestige and 9000 series units (like the BRI958, BRI957, and BRI955) fail due to a specific component failure. If you can hear the fan spinning and the power is on, but the pulse button does nothing, you likely have a shorted IGBT transistor.
