LG 42PC3D-UD Z-Sus Help
|
Can't Post

Trying to troubleshoot an LG 42PC3D-UD. When I got it, it would turn on but there would be black on some of the screen. Not defined lines but a bleeding of sorts. Did some reading and was pointed to the Z-Sus board. While in the back I noticed seven capacitors swollen on the main board in the center top. One of the fuses on the Z-sus was blown as well. I figured that the caps blew and in turn zapped the fuse or visa versa. So, I replaced all caps and fuse. Turn the unit on and it clicks then turns right off. I pulled the good fuse that I put in and tried it again and it will come on but with the same bleeding. To the question: how do I verify it is my Z-sus board to still something with the main board? There were one or two caps of the same specs in the same area of the bad ones but they weren't swollen like the others, should I suspect those to be bad too? Any help would be great! Thanks - SK
