my SONOS Play 1 speaker does not power up. I opened it up and found blue Capacitor 360 was blackened and it looks as though the square black component nearby, 03N60C3 / GA1 530 also looks fused. I have attached some pictures. Any idea where I might find the replacement parts. Thank you very much in anticipation.
@chriselvin The TO-251 and TO-252 are just the component package type as can been seen in this link The one in your device is a 03N60C3 in a TO-252 package See the component connections to the board - TO-251 all 3 legs are on one side The TO-252 has 2 on one side and it looks like the case may be connected on the other side.
