Panasonic Viera Plasma Showing Black Box On Screen Can't Post

I have gotten a free Panasonic Viera TH-PX600U from a friend and it has some problems I would like to fix.


The problem is a large black rectangle with green lines surrounding it on the screen. The screen works fine otherwise, picture is good and sound is good.

My immediate response to the problem was to screw the metal back panel off and take a look at the capacitors on the logic board. But everything looked fine to me, no blown caps, no bulging caps could be seen anywhere on the TV they all look fine. I did notice a lot of dust and will try getting rid of that later today and making sure all connections are making good contact. I also heard playing with the CC settings and turning them off could do it, I tried that it did nothing.

But if anyone has worked on these Panasonic Viera TVs and recognizes this problem and has an idea please share with me what you think could be causing this. There isn't any physical damage to the unit so I'd like to think it is a circuitry problem.

NOT a Closed Caption issue.

I'm just assuming 50" (same should apply to other sizes).
