Jul 28 at 14:09 comment added Spehro 'speff' Pefhany Are you sure the capacitor is actually 22uF and not, say, 22nF? If so it would oscillate at a high frequency and the LED would appear to be on continuously.
Jul 28 at 13:59 comment added balu Hey, thank you for your answer. I checked every component and added the measured Voltages into my question.
