Panasonic TH-50PZ77U 1 1/4" inch vertical line

This problem is usually the ribbon cable connection at the top of the stripe. Reseat the cable first. The other possibility is the panel itself, but that is rare.
Keep us posted.

Is there a specific way to remove the ribbon before attempted removing it?

Once you open up the unit, you should see a series of flat orage cables coming from the panel itself. These are the cables that can have poor connections. CAREFULLY remove them by releasing the connector "lock" and reseat them inside the connector. Re-lock the connector and try the set. If that fails, you should have the set examined as specialized equipment will be necessary to trace this problem.

I have a 52 inch Samsung TV, on the screen have solid, color vertical lines on the right, about 1/8 wide, on the same time the half of screen blink on the right too.


not knowing the model... i will try to help with this common samsung issue, if i can. / unplug the tv, and wait a few minutes to avoid shocks. / remove back panel. you will see several ribbon connectors, (about an 1" to 1 1/2" wide) usually near the bottom. / carefully remove the ribbon (ONE AT A TIME) and clean the contacts GENTLY with a pencil eraser. (DO NOT use chemicals) / reinsert the ribbons and try the tv. // vertical stripes are almost always the result of poor contact between ribbon and socket. / NOTE!. you can do a quick test before opening the set by [carefully!!!!] twisting the screen and watch to see if the vertical stripes change or disappear. / if the stripes change, bet on it being the ribbon contact problem.//// hope this helps, it has worked on a number of TVs.------Jay

We have a one yr old panasonic Ciera 42inch recently we started having a blue and pink line appear vertically down the centre of the screen, this lasted a few days and it has now turned into a thick black...


Hello,

All plasma TVs have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.


I hope this will help out in solving the problem ......

Panasonic 50PZ80U vertical lines


if these lines are solid black then your panel is probably bad. being six months old it is still under manufacturer warranty. they should be able to fix it for you for free. if they are not able to assist you then there is a way that you can check to see if the panel is bad. mark on the tv with a sticker or peice of tape where the lines are. then take the back of the tv off. find out where the lines are and it should line up with a ribbon cable. unscrew the ribbon cable and take it loose. it will be attached to the panel so dont pull to hard. there will be what looks like a little dark strip on the ribbon cable. these little strips have micro chips in them. look closely at the ribbon cable and if you see and arc spot or a burn spot then the panel is bad. look at one that is good for comparison. if this is bad and you are not able to get it warrantied then the tv is not worth fixing. the panels for these things cost about as much as a brand new tv would. hope this was helpful.

TV Screen Stripes


NOt very clear.....

Multiple stripes all over the screen? Vertical or horizontal?

If it's only like an inch vertical lines put a mark on the cabinet where exaclty the line is, turn off the TV then open the back, you'll see lots of ribbon wires (gold color) from the plasma panel it self going to buffer boards, using the mark find the closest ribbon wire where the line is showing then remove and clean the contacts, make sure to reseat it properly when putting it back otherwise you'll just add more lines or black bar on the screen if pins are not seating properly.
But do not be afraid if the lines get worst just turn the power off right away and reaset the ribbon wire till you get it correctly.

CAUTION;
DO NOT try to do this while the TV is on oherwise you'll burn COF (Chip on film) on the panel and you'll end up replacing the whole PDP.

Good luck!

42" Panasonic Plasma - Vertical red stripe 6" from left side


We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?
