hey all., how are you,
my situation is this, i have a samsung plasma PS42s5h and the power supply has no vs voltage. it however has vd.
once i taken the power supply out, i soon relised tracing the problem with the 206v dc vs output, as i traced the parts, both diode transistors where short. then from the diodes, the tracks lead to the switching transformer. prior to the transformer, the switching transistor was also short. and a 5amp fuse blew. now im not to worried about the diodes, but the switching transistor is what im worried about, the original one is a stw26nm50, but i could only get my hands on a stw26nm60, im not to sure if it will work ok. also on the other side of the board, it has the same transformer and a nm60 as well. i just wonder why one side of the board has a nm50 and the other is a nm60.
anyway my quesition is can i put in a stw26nm60 instead of a stw26nm50?
