The device turns on, lighting only the colored LEDs and then turns off. | power supply, SMD diode (with flashing) connected to pin 15 of IC1501 | Diode replacement. NOTE: I didn't find the specifications for this diode, I put a board cutout on it and it worked. But based on the characteristics of wsound it is positioned in the circuit and the diode impedance test, I came to the conclusion that it is a fast diode, with a higher voltage and is not a schottky. If anyone discovers a specific diode that is correct, please repost a tip informing us to help everyone. | Gênios Eletrônica SJ |
