Confusion with Panasonic A boards

Re: Confusion with Panasonic A boards

I broke down today and ordered the YSUS and ZSUS boards. So if this doesn't work, then I have only the lower buffer boards to replace and every board has been replaced. I'll post my findings once my boards get here.

Re: Confusion with Panasonic A boards

OK, I received the Ysus and Zsus boards and they worked. But as stated above, I think this tv was a dumping ground for bad boards. The tv turns on and works but I have black lines. To me I think the panel is shot but I'll let you all decide. The only boards that haven't been replaced are the lower buffer boards. Can the buffers cause this problem? I'm thinking not. Pictures attached.


EDIT: I tried to reseat the ribbon cables on the Ysus or SN board as they call it.

Keep trying to reseat the SN ribbons to panel . Thay can be tricky, you can feel them wedge in. Must sure TV is off, where the lines are will line up the ribbon, they're the ones to focus on.

where there are no lines, compare those ribbons to the bad ones, they do have side markers to help determine in they are in and straight.

Thanks, I'll play with it tonight.

So does this mean my panel is good?

Hard to say, if you can't get rid of those lines then no so good. Flex cables could be damaged or missing contacts?

You were correct. I reseated the ribbon cables about half a dozen times and voila working tv. Only had to replace the SN, SS, and the A boards. Into it for $300. Too much money but I wasn't going to let it get the best of me.

Thanks again

So which A board did you end up using.

I needed an AP board. Couldn't find one. I used an AT board. Could have used an AR board but I would have had to remove the DB9 port. How I came to picking that board was by searching the panel sticker on shopjimmy. It gave me those boards. They didn't have any stock so I had to resort to Ebay.
