Emerson LC320EM8 LCD HDTV red vertical lines on right 1/3 of screen

The set was bought in May of 2007 and has shown a red vertical line from top to bottom about a pixel wide with all connections (HDMI, Component, RF tuner) for a month or so. This line will disappear after the tv has been on for a while. Now there is a second line that just appeared yesterday to the left of it. I can take pictures if it is helpful. I'd rather not have to send it in for service if I don't have to due to the cost to ship it and the possiblility that no problem will be found.

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

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.

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

SOURCE: Line in middle of LCD screen

I too had a black line horizontally across the screen (on a 52" d62). It was brand new and was as if the screen had been "pinched" at the end of the line and it radiated outward (in my case, the "pinch" was at the extreme left and line went out to the right, like a crack).

Mine was a factory defect (right out of the box) and was replaced (2 yr now and no issues). This line of yours may have been there from the start and maybe you just didn't notice it?? Not a slam, just an observation.

A red vertical line that doesn't go away. Is it a tube or what. TV is about 3 yr. old.


A LCD does not have any tubes in it and the red vertical line is a driver in the TV that has gone bad.

Vertical red line through screen


This is a problem within the screen, probably the connection from the internal ribbon connector to the display. Unfortunatly the only way to repair this is to have the screen replaced.

Red vertical line down right side of the screen


hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

Vertical line on LCD TV Panel


Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan
