Mine also died, just 2 weeks ago.
Repair center came out, tried swapping out the Logic Board, and it didn't fix it.
Said I needed a new panel and that included everything other then the logic board, cost would be $900.
Its unacceptable for a TV with less then 200 panel hours on it.
I want to fix it, but no one on any of the plasma forums online have any suggestions. Just to buy a new $1500 tv instead of trying to troubleshoot it.
Here's my original problem thread:
We purchased our 5084 brand new, like 3 years ago.
Since then it has only ever been used for BluRay movies. Im going to guess it has around 300 hours on it.
After we had it about 4 months we had a loud buzzing noise and a service tech did something and it fixed the problem.
Tonight I went and turned it on. And after you hear everything click on it went POP. Sounded like the side farthest from the power cord.
And well, I have no picture now. Well, thats a lie. I do have a picture, but I get this on every input. The center rectangle refreshes. And the lines in it scroll from left to right.
It also has a green and blue sparkle that you can see in the photos all over the black.
The tech that came out said the "panel is bad" and "this is all the "panel."" He was referring to everything except the main logic board. He did try a new logic board, and it didn't solve anything.
Here's link to a video showing it "refreshing"
