I spent just under $1,000 it was 750 and 200 for freight costs...foolishly took the risk thinking it would be no major issue.

Did you say you would pay ~$150 for the TV or the a board?

Hey on your tv why dont you try disconnecting the ribbon that attaches the bottom board middle to the board under the section you are having the problem with and then reconnect and any other ribbons that may connect to that board as well and reconnect as well. Then power up. If still the same image problem persists heres what to try to rule out the panel.

Pull plug.
Disconnect one at a time the connections between the bottom board and the panel. Only try this under the section that is giving you the distorted image, as this is the problem area.
Then power up.

Notice there are 4 connections to each C board. (C board) is what we call these long boards on the bottom. If you get most of the image back when one ribbon connector is disconnected from the panel, it will most definatly be a panel problem.

Panasonic PDP panel lower C works in a series like tandem. If one IC chip on those ribbons short in such a way, it will knock out the driver controls for that entre length of the panel C board.

If this doesnt make sense, let us know and will elaborate further.

Re: Panasonic 65VT60 Vertical lines HELP

Ok well i just tried the first step....at least to the tune of un/reseating the short ribbon between the middle and right c board under the area with the issue. As far as any other ribbons on that board i did not see them, at least not white ones of the same type as the other ones ive been exclusively trying out. I had hope for a moment as i noticed that board was not screwed down well the screw was completely loose and that gave me hope as well but all that has changed is the lines now appear ever so slightly different and kind of rotate at a high speed between one set of lines and another...at least thats the best i can describe it but i am posting two pictures to illustrate this.

I am a little lost on the C board instructions, the 4 connections you are referring to would be on the top or bottom of the board? I am posting a picture of that board as well and the only ribbon connectors i see are at the very bottom of it near flush against the metal and that whole area is in a little "half pipe" shaped area of metal and i can't imagine you someone could access the connector honestly.

Click here and the first three pics are the ones i referenced. The first is the c board i think and the second two show the difference in the grouping of lines and you should notice that the green lines seem to go away in one as opposed to before when it was a completely solid static grouping. https://www.icloud.com/photostream/#A2GY8gBYdJhhg

Re: Panasonic 65VT60 Vertical lines HELP

Ok thats a dead giveaway. Someone has been in the tv before. If rhe screws that hold down that C board were loose someone had to be tampering with it. As far as the connections. Yes the very bottom ribbons that go into the panel. These are the ones. Im half tempted to rhink the ribbons going into the board may in fact not be seated correctly.
Do you feel comfortable removing that board and reseating the ribbons?

Re: Panasonic 65VT60 Vertical lines HELP

Btw dont touch the boards on the side of the tv. Those are ok. Were focusing on that bottom board under the screen in the affected area only

Yea i am 100% positive someone has been in it...saw toolmarks near a couple screw holes and the one by the digital camera was literally stripped smooth and shiny and necessitated pliers, it was suprisingly clean inside though, i figured that the company that sold it was trying to do exactly what i am to make more than they paid.

What is the process of removing the board, a couple screws and lift? Is there any play in the cables connected at the bottom?

Re: Panasonic 65VT60 Vertical lines HELP

No there is prob no play in the ribbons. Its really tricky and involved. Before uou go into it that far consider the A board replacement as it could be the source of rhe problem. Unless the company already.tried that.

Re: Panasonic 65VT60 Vertical lines HELP

No the c board.is held on my like 4 or 5 screws. The ribbons clip in in similar manner as the white ribbons do. But then you have to lift the board out. Be careful asnthe panel ribbons may try to grab the board still. Its tricky.

Re: Panasonic 65VT60 Vertical lines HELP

I just checked out the way this c1 board mounts in a cracked screen Panasonic UT50 series plasma I have at my shop. Which is very similar to your design. I pulled the board but its really tricky trying to reinstall. There is no play in the address ribbons at the bottom of the screen. You kind of have wiggle them back in the board slowly and very gently as they all have to seat at the same time. And I was incorrect stating there are four connections to a c board. There are five.

Re: Panasonic 65VT60 Vertical lines HELP

Thanks again to y'all for the insight. I was wandering as far as the issue i seemed to have with this set, is it something that would come off the line like this every time & this issue will always present itself instantly or is it something that can happen with a plasma after a period of time of functioning fine as well? Is there anything to look out for with future sets like any behaviors that would show up as precursors to the panel failing like this or not really and it can just be fine one second and turn it on the next and its failed?

Re: Panasonic 65VT60 Vertical lines HELP

No precursors. One moment working, next dead. Though this fault would only have occurred with someone tampering with the set, IMO. Single segment bars are spontaneous.

Re: Panasonic 65VT60 Vertical lines HELP

The correct way to remove the lower connectors is to strip down enough so they are fully accessible, remove the two screws on each one that secure it to the panel (heatsinks), lift the latch on the C board, then slightly raise the ribbon and withdraw it. If you try and just unscrew the C board leaving all 4 ribbons attached there is a danger of tearing one. They are fairly robust but I would do one at a time as described above. Leave the C board screws loose until you've reseated all 4, then screw the heatsinks down and finish by screwing down the C board screws.

I used to do 4 or 5 of these a day some days when we did warranty repair work as we had to replace a lot of PDP panels either for this failure or cracked panels, once you get the knack of it it's easy.

I'd try that method to rule out that the previous repairer hasn't fitted it wrong, but I have to say that does look like a panel failure. I think the repairer has tried swapping the C board and finally condemned the display.

agreed it probably had a single segment out to start with and then somebody started fooling around with the C board and then with the power on shorted the rest of the ribbon IC'S out
