I have a multimeter and dead CD player circuit board. the board died because of too much power from high power ac adapter. weird smell coming from area where surface mount transistor is. it looks like transistor got busted. how do i use multimeter to see if transistor dead or not. also how i measure power of transistor? i want to replace with transistor from other dead cd player or dead psx\ps2 board. help please.
does transistor 1 look busted? or is supposed to be like that?
transistor 2 is near that looks like exact same execpt without crack. is that broken?
Thanks very much for info it helped very much! But can i replace with any transistor or does it have to be same and how can i measure power of transistor.
