Panasonic plasma while vertical line

[Rmasters3]

Had a seven blink code with a P60U50, 60" plasma made in 2012 or so. I have replaced the SD, SC & SU boards with known good ones. Working now, but with two issues:

1) Thin black horizontal lines full width of screen. Had these in several places, but cleaning the ribbon connectors between buffer boards and display ribbons eliminated all but one group. Repeated cleaning of that connection haven't fixed it. Any suggestions?

2) One, vertical white/bright line in upper half of screen, one location to left of center. This is a bright, white line, 1/8 to 1/4" wide, with a program running and on start-up. Tried cleaning lower C1 connector that's directly under the line area, but so far, no go. This white line extends from screen top to middle of display--not sure if occasionally it flickers through full screen top to bottom.

FWIW: Previous owner said his son hit the TV screen with his air-soft gun, so display could be damaged.

Set is nice enough, I'd hate part it out, but won't replace the display.

Re: Panasonic plasma while vertical line

Horizontal lines are most likely from misaligned panel ribbons when you installed the sd/su boards. Turn the TV off and reseat the ribbons that align with those. The ribbons can be tricky and need to be in straight and all the way in.

As for the centre band, sounds like could be bad panel. maybe upload a picture of it.

Re: Panasonic plasma while vertical line

The picture of the single vertical line in the information you sent would indicate the PDP is bad. The horizontal lines seem to indicate an issue with the SU (upper) board. The replacement SU was supposed to have come from a new set with a screen broken in shipping. Thanks for your input.

Re: Panasonic plasma while vertical line

I was just thinking of something else to try and that is to go into service mode, then select option, then mirror. You could try a vertical flip and a horizontal flip of the image.

If the bar stays exactly in the same position then that would confirm panel, if it moves then A board. Could also try replacing the C buffer that aligns with it but that's probably less likely, one of those things you need to decide whether spending the money to try it or not

Thanks for that. I'll look into this, but I'm in over my head here--can you reference the manual page where this procedure is outlined? Thanksi

Could we get a picture of the fault?

I'll lead you to page 2 Contents, I'm confident the rest is self explanatory as I've given you the key words and even in the contents it will be staring you in the face

Re: Panasonic plasma while vertical line

I'll post a photo of the fault when I can turn the set around to see the screen.

Re: Panasonic plasma while vertical line

I have been able to navigate to the Option in the Service mode, and it shows ROM, getting from there to Mirrror isn't something I've been able to do--tried inputting numbers from remote keyboard, remote directional keys, volume, channel, etc. How do I get Mirror to show display beside 00 Normal.

FWIW: I get RFI on an AM radio whenever I turn the TV on.

Yes, you are dealing with a rookie here.

probably not intuitive but using the remote, once in option, push 4 for sub menu select, when you see mirror use vol up or down on remote and that will cycle the mirrors

(on screen it gives the controls in the box below the menu)

So 1,2 are for the main menu items so scroll through until "option" mirror is a sub menu of that so use 3,4 to scroll to get "mirror" up, then vol up/down to cycle those. 00,01,02.

good luck

just tried it on mine.

Re: Panasonic plasma while vertical line

I did finally figure it out--the white line remains in place (right about middle of the screen) when the picture is reversed, disappears when inverted.

Still have the RFI on AM radio.

Re: Panasonic plasma while vertical line

Can we get some screen shots of all 3 positions at some stage? So on a vertical flip, you have no white bar, normal image but upside down, on horizontal it's about the same(or maybe it shifted slightly?) If it was dead centre then it would not shift on the horizontal.

that's interesting, 1. if it's panel it should be there in the same spot 2. if it's A board I would expect it to move to the bottom half of screen.

But for it to disappear, the panel would need to be good but how did it go? That's my question.

there are some test patterns you can scroll through in "aging" i wonder how the display goes there?

Re: Panasonic plasma while vertical line

I'm not concerned with RFI, the back is off the TV ?

Re: Panasonic plasma while vertical line

The back is off the TV.

I have the set in a man-cave workshop where I tinker with stuff. The 60" set is unwieldy and turning it around for screen shots, given how I have it on the workbench, is difficult (set has no base). Top that off with my bad back that restricts how much it is wise for me to lift. I'm concerned about if falling.

Should I be running playing a DVD so I have on-screen images while I play with this?

Hmmm, yeah 60" is a fair bit of TV. I think some sort of image would be handy to confirm. Unfortunate you have no base, yes you'd need to be careful having something that large laid flat, you'd want an assistant for sure.

With the back off it would be pumping out RFI, Tom knows more about that, he joked about me having my cover off and HAM operators getting annoyed.

Well at some stage I think we need some shots, so you just have a blank dull screen is that the deal when you did the mirror.

I would run some content through it and do that mirror again. Tom or someone else may pick this up, if you continue, otherwise I'll catch up later

I really need to hit the sack at 1am here

Re: Panasonic plasma while vertical line

It apparently was the PDP, mirroring the picture moved the white line not at all. I ended up selling the set As-Is (guy is going to hang it in his garage workshop where he can see it at a glance from across the room).

So: Thank you very much for the help. I learned something, enjoyed it and will be back again.

well although not a good result as least there is closure. that mirror function is a handy tool for a situation like this
