I replaced the two original MOSFETS which had originally failed, applied thermal grease and checked the board by plugging it into the wall. The MOSFETS has finally arrived from China yesterday after an agonizing wait so this morning I wasted no time and got to work. 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? 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 was able to locate the data sheet for the failed MOSFET transistors (S)_REV 1.0_20100809.pdf but I don't particularly understand everything. These 2 MOSFETS has the following text engraved on it. My multimeter kept giving me 0 on the continuity test on every leg regardless of polarity. Eventually I located 2 MOSFET transistors when was reading short no matter how I tested it. I then tested the diodes and bridge rectifier which all turned out to be fine. At this point I knew there must be a short someone in the PCB causing the fuse to blow. I then replaced the fuse however it went straight away as soon as the power was switched on from the wall. I popped oven the back cover and tested the fuse on the switching power supply board which was blown. I have recently acquired a faulty LCD TV that does not power on.
