Question about Panasonic 50" 720p Flat-Panel Plasma HDTV

1 Answer

I have a 50-inch panasonic plasma tv that occasionally shows a solid black vertical bar near the center of the TV screen, 3 inches wide, from the top of the screen to the bottom. When the bar goes away, I can see distorted color lines, especially red, where the bar was. This problem is getting worse. What is causing this and what needs to be done? My manufacture's warranty expires in November, 2010. Any help would be appreciated. Thank you. John

So the warranty expired in 2010, some 7 years ago!
The Plasma driver chip driving the centre portion has failed.
There is one cure, replace the screen.

it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.

SOURCE: Parallel vertical lines through left side of Panasonic Plasma tv

This sounds like one of the driver boards at the bottom or top of the screen has an intermittent fault. The set will have to be taken in to a service centre.

SOURCE: I have a verticle black line about 3 inches wide on my panasonic

Normally when a line appears on the screen of a plasma or LCD it indicates the TV needs repair. There are circuit boards inside the set that, if bad, will cause problems with the picture. The only troubleshooting the manufacturer will offer is to unplug the TV for 30 minutes. If that doesn't solve the issue, the unit needs service.

Call Panasonic at 800-211-7262 to see what they're willing to do for you. If you're under warranty they will service the TV for sure. If you're out of warranty they still might give you a break--they've been known to do that.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

SOURCE: solid black vertical line

You could have one of three problems. One is really expensive to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went bad. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable2_bing.gif and clean it off a bit and put it back. If its still there, you have a deeper problem.

The buffer boards are located across the bottow when you take the back off. About 3 inches wide. Sometimes they are on the top as well.

Picture just has black bar down the middle of the screen.

That is probably a faulty segment display.
Replacing the screen will fix it.
