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: thin horizontal line, Panasonic TH-50PX60U

unfortunately the panel is bad. I've worked on a number of these panels to know that symptom. I checked with panasonic and the warranty is one year parts and labor. you may be able to get panasonic to fix it if you still have warranty (purchased within 1 yr.) or check with your state's implied warranty. you might qualify for warranty repair under this implied warranty. call panasonic when you find out about the state's rules.

SOURCE: my plasma has a thin black horizontal line

You can either have a bad Y-Upper buffer board, or dirty contacts on the plug associated with the horizontal line. Best to have a service company look at it.
