Hi all,
I have recently acquired a faulty LCD TV that does not power on. I popped oven the back cover and tested the fuse on the switching power supply board which was blown. I then replaced the fuse however it went straight away as soon as the power was switched on from the wall. At this point I knew there must be a short someone in the PCB causing the fuse to blow.
I then tested the diodes and bridge rectifier which all turned out to be fine. Eventually I located 2 MOSFET transistors when was reading short no matter how I tested it. My multimeter kept giving me 0 on the continuity test on every leg regardless of polarity.
These 2 MOSFETS has the following text engraved on it...
NIKOS
P1260ATF
SUE2N1A01

I was able to locate the data sheet for the failed MOSFET transistors http://www3.use.com.tw/webdata/niko/P1260ATF(S)_REV 1.0_20100809.pdf but I don't particularly understand everything. I have some experience with electronics such as replacing capacitors but this is the first time I'm dealing with these types of transistors.
I tried to source an exact replacement online but I'm not having much luck, apart from a few sellers from China who has a minimum order of 10! Is there an alternative transistor that I can use or something?
Much appreciated!
