Re: HP PL4260N ysus or zsus

Thanks. I looked and the number is 6871QZH956B. Therefore i should replace the zsus correct? I attached three more pics of the tuner board. Is this something to worry about, or a way to test these parts, or is it fine? To me it looks bad, but I dont really know what I'm looking at. Everything else looks clean and new except those two areas. Thanks again....

Hello, this is my first time on this forum, and I've read a lot of information but can't seem to find the answer i'm looking for. I have a HP PL4260N plasma tv and I have the no picture but the sound works fine. I found that one of the fuses (the top one of the two) on the zsus board (the board on the right) is blown. I read everywhere that people replace the ysus board and it fixes the problem. Is there any test I can do to see which board is the faulty board, or is it the zsus because that's where the fuse is blown?

Also i noticed what appears to be burnt or something on the tuner...
