My in-laws' TV went out, I helped them purchase another, but I decided to tinker with the old one just to see if by chance it was something simple. I am by no means an expert in electronics repair, so this site was extremely helpful. I found a blown fuse on the neutral side (circled bottom left in attached picture) was the issue all along and after replacing it, it is now up and running perfectly. I do have a few questions though, please.
--Why is there a fuse on the neutral? I also wonder what could have blown it.
--After I replaced the fuse, I plugged in the power supply with the back still off of the TV, and a "pop" and small flash came out of the left of the two black square components that I have a small scribbled circle on (top left in attached picture.) When this occurred, I expected I had blown a fuse again, so I was going to check the voltage of what I thought was the rectifier. I put my test probes on the two outside legs of the thing covered by a heat sink in the middle left portion of the attached picture, which I placed two red lines on to indicate. Is this the rectifier? When I touched the probes to those legs, a small arc occurred that scared the crap out of me.
--I then decided to stop with the probing and hook it back up to see if it worked. Although I didn't expect it to, it did and has been working fine since.
Thank you to all who contribute to this site. I found it very helpful, and I have since began trying to learn more about electrical components and theory.
