I recently experience the same problem with my Vizio P50HCTV10A plasma, "Pop of Death". However, I still have a picture (it's very dim) and the sound is fine. I am looking to take your advice and replace the boards, but was wondering if you had any further instructions on how to do so? I'm no tech, but I'd like to do this myself. How difficult is this to do? Also, I'm having trouble locating the parts you listed: Z sustainer board: #6871QZH044B and Y sustainer board: #6871QYH039B. Any suggestions? Also, I noticed when I pressed the info button onscreen I get the message: "Fan1Error Fan2Error" Any thoughts?
