I have a 50 inch Samsung plasma HDTV model LNT4071FXXAA version SS02 it has a small approximately 16th inch vertical line starting at the bottom of the screen and going about 4 or 5 inches up When looking directly at the tv you cant see the lines but from any angle you can see the line as white or colored The line has very slowly grown upward about a quarter inch in a month From the research Ive done all the lines that I have seen have been much larger Should I be worried about my tv going out Would it be an easy fix

A possible simple solution , do you have large speakers close to the TV? The magnetic field in non shielded speakers can cause this problem ,

Open the back of the tv. Inside you will find a series of connectors with ribbon connectors along the screen edge. look where the line is on the screen and open the ribbon cable clamp closest to the line. Move the ribbon cable a little and re-clamp it. Sometimes a little corrosion creates a bad connection.

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: Vertical line on side of LCD TV

Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

SOURCE: Vertical lines on my 40 inch lcd mitsubishi hdtv 1080.

I assume your Misubishi is not close to anything electrical. However, it sounds like you have had an interference for some time. This will ineviteably cause the HDTV LCD to collapse. LCD's don't respond well close to heat. Is there a vent close? LCD's do well in a properly vented area but with all this said.......they will pick up interference from anything electrical. A few questions to ask ones self........are there any wireless devices or chargers close to the LCD? Might there be an oven, a/c unit or other wiring with 220 volts anywhere close to the LCD such as in the wall?
The Mitsubishi LT is a very reliable, multi component ready set that allows great viewing with surround sound. However, stop and think about this interference. It is not something in the unit. It is an interference. Look hard and when you've discovered it.....you won't believe how crystal clear this set will be.
Let me know what you find...Thanks for using Fixya and add any comments that may help us help you.

Bad/Going Bad/Will go horribly bad TCON board (small circuit board sitting at the top of the panel in the back).

Most likely, the whole panel will need to be replaced in order to rectify the issue.

SOURCE: 42 inch samsung plasma tv black vertical lines

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

LG plasma 50 inch tv with a fine vertical black line in the center of the screen that runs from the top of the screen to the bottom


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Colored "snow" vertical line an inch thick on Samsung plasma


That is the sustain and buffer boards. Try to find a repair shop to repair on the component/board level because the cost of new boards out weighs the replacement cost.

Samsung 50 in. HPS5033X/XAA colored lines running vertically and won't go away.


How wide are the lines. Do they change width? Where on the screen are they located?Connections on the c boards at the bottom to the panel flex cables or bad c board itself can cause 2 inch wide verticle bar. Before touching these connectors be sure power supply is disconnected from the 2 sustain boards on the sides. If you don't there will be an arc that will destroy the flex cable thus you will have to replace the panel. If C boards or connections don't fix it the replace the plasma panel. If the lines are thin lines then panel is likely bad. Contact Panasonic even if out of warr they may help.
