Hi everyone, this is my first post.
I have an LG 55LE5400 TV that's worked fine until a few days ago. No storms, nothing to cause a power surge (that I know of), but last week while my wife and I were reading, we heard a POP and saw a flash behind the TV. I pulled out the power supply (picture attached) and the fuse lower left of the board was blown. I went to our local electronics store and bought a handful of replacement fuses. The first one I put in blew the instant I connected power.
I've just gotten into electronic repair and I'm pretty sure that after testing the capacitors I'm above my head. I didn't plan to have my first project be a 55 inch TV.
So, I'm hoping someone here can help me out. I've got a DMM, plenty of patience, and if I wasn't motivated to learn before, I sure am now in light of possibly having to buy a new TV or a new power supply. I'd rather find the screwy part and replace it than spend loads of cash for a 25 cent piece of equipment.
Thanks is advance.
(I checked the SMPS tutorial as well and am not sure whether it applies to me or not)
