Like I said in the other thread it's a P-channel MOSFET. The person in the other thread did not listen and replaced it with a PNP transistor which is the wrong type of component. Here is a component that will likely work: http://www.digikey.com/product-detail/en/DMP3098L-7/DMP3098LDICT-ND/1964773
With that said, a chip that cratered like that probably took something else out with it, or something else failed first causing that to fail second. So order a few of those guys because it's likely it'll fail again before you find the real culprit. By looking at the traces I see the component is between the output of the supply (the brown component, it's a ceramic capacitor) and a large electrolytic capacitor (the silver can). This looks to be some kind of power down circuit, to reduce standby power when not in use. To check if there is something else shorted downstream you can use an ohmmeter across the electrolytic capacitor to see if it's shorted (low resistance). First remove the fried Q3. If across the cap is shorted, then you will need to figure out what part is shorted and fix that too. It won't be the electrolytic cap but something else connected to that supply. Let us know what your ohmmeter reads across that capacitor. Try the test leads both directions, too. ------------------------------------------------------------------------ rpress's Profile: http://forums.slimdevices.com/member.php?userid=31544 View this thread: http://forums.slimdevices.com/showthread.php?t=103458 _______________________________________________ Radio mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/radio
