Hello,
I have a Panasonic Viera TH50PZ85U that I inherited from a client that asked me to fix it. I told him that I don't have enough experience with television repair to offer him any real guarantee of anything, and such I would not feel comfortable charging him for a repair. Upon this news, he simply gave it to me.
I tell you that, because I want you to know that I have zero knowledge of the backstory. I do know that he recently moved and it worked before the move.
What I have tried / Noticed
There is an INTENSE buzzing that SEEMS to be coming from the bottom right corner (from the back) of the unit. It's a strange, two-toned electric hum that varies in intensity. I have also noted that it appears to die down momentarily if you change inputs using the back panel, but immediately drones again once the input has been selected.
I note that the power light comes on red and stays lit.
Removing the back panel, I note that both SC and SS board LED are lit green.
Removing the A5 connector does nothing for the issue and does not display the white screen.
I have tightened all screws and verified all connectors are seated, even going so far as to reseat several of them.
My gut feeling at this point is that it is in fact a failed panel, and no further troubleshooting will help, it is simply a land-fill piece.
I would sincerely appreciate anyone elses input on this, and am more than willing to provide whatever you would like.
