Ok, well, I've always been one to find answers online, and this is the first time I've needed this type of help, but here we go. I have a degree in Mech Eng, so I have a LITTLE Elec Eng experience...ok, I took one Intro to EE class, and admit I don't know a whole lot about electronics, except you shouldn't get them wet. Well, maybe a bit more than that. My parents have a Sylvania LCD Model 6620LCT TV that quit working. Me, being inquisitive, took it apart and found a 4 amp fuse was blown. My dad ran out to check NAPA for a new fuse and came home with a 2 amp one. We tried it anyway, and of course, it blew. Now, rememeber, I'm not the best with electronics, but I like fixing things. My dad suggests we use some aluminum foil to complete the circuit and see if it works at least, and then we can get a good fuse later. I was leary, but we tried it and that proceeded to blow something that then created a smoke cloud. I don't know what the part is, but I contacted sylvania and they sent me to someone who sent me the service manual that lists the parts. Sorry, this is getting long.... I used the part numbers printed on the main circuit board to cross reference the parts list and found it to be a "LINE FILTER 5.0MH 6Y075" At least I hope. I ordered one off funai for $4.35, which seems reasonable enough if I can fix the TV.
Now since I don't really know what I'm doing, before I go and resolder a line filter in and replace the fuse to just blow both again...is there anything else I can check or do? If that doesn't work, how can I diagnose the problem myself? I'll try to provide any photos or information needed.
Thanks in advance...if nothing, I'm hoping to learn a bit.
