A 12" high by 4" wide block of colored vertical lines in middle of screen
When an image is on the screen, this block of vertical lines appears in the image in red, green and blue colors. I am seeing it on all inputs: video, s-video and component and from all sources (cable, satellite and DVD) so I think it must be in the TV circuitry.

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.
Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.
Laptop screen display problems occur for many different reasons. Some issues need professional attention, but others can be repaired by the owner. A screen that displays vertical lines often means that there is a problem with the video cable connection to the LCD screen, or the cable itself. In order to repair this problem, the display screen must be disassembled. If you feel confident that this task is within your realm of expertise, follow the steps below to remove your laptop's LCD panel and fix the vertical line problem on your laptop screen.
1. Remove the rubber seals covering the screws on your screen's outer frame using a flat-head screwdriver. Remove the screws, then carefully pry the frame from the screen using your fingers. Release the plastic latches holding the framing in place, then remove.
2. Remove the screws holding the screen to the support brackets. You will see the video cable, which is attached to the back of the LCD screen. Try unplugging and reconnecting this cable, making sure that it is seated properly. If the problem was the connection, this may solve the vertical line issue.
3. Turn on the laptop. Move the video cable around a bit, without moving or touching the screen. Check the screen to see if the display image changes at all. If it does, the problem may be with the cable itself. 4. Move the laptop screen around to see if this affects the display. If so, the problem is most likely with the LCD screen itself, not the video cable. Replacing the screen will be necessary.
To answer your concern, all you have to do is to change the setting of your aspect ratio on your TV.
Here is my suggested way to procede:
1. Apply 1080i signal, which should produce an oversized HD image on ColorStream1or 2. 2. Select an HD channel that is broadcasting standard 4:3 image, not wide screen. 3. Switch to the Service Mode ( Please refer to the above links). In the Service mode, press channel up/down to find the Adjustment parameters needed for the following steps.
4. Adjust HIT with volume up/down control for the image height to 22.5 inches.
6. Adjust WID for image width of 30 inches, (22.5*4/3) 7. Adjust HPOS to center the image. 8. Adjust PARA and TRAP to minimize geometric distortion. 9. Switch into Convergence mode and Adjust VLIN to get equally spaced horizontal grid lines. 10. Measure the length of the central grid lines and note the number of horizontal and vertical grid lines. This information is used to create an overlay grid. 11. Create the overlay grid on 40x25 x0.003 inch clear Acetate sheet, which you can get at the Art Supply store for under $2. Draw the grid with a fine line erasable pen. Draw vertical and horizontal lines through the center of the sheet so that the lengths are the same as the central grid lines. Now draw the grid so that it has the same number of lines as the convergence grid but are equally spaced, with the outer ones at the ends of the central lines. 12. Cut off about 1/4 inch from the right side of the sheet so that the sheet can lay flat against the screen, which is slightly less than 40 inches. 13. Put a reference mark on the TV frame 2.5 inches down from the upper left side of the screen. 14. Place the overlay on the screen so that the upper edge lines up with the reference mark. The overlay sticks by electrostatic attraction. 15. Use convergence controls to remove grid distortion and converge grid colors. Refer to the Anamorphic link for details. 16. Enjoy 1080i.
Other Comments: I didn't realize I could create the overlay grid before placing the Acetate sheet on the TV screen, until I finished drawing the grid with the sheet placed on the screen. I added grid lines as called for in the procedure. I'm sure this method took much longer no only to draw the lines but some of them were difficult to see.
Part way through the convergence procedure, I became concerned that the image width was off since I did my screen adjustment with wide screen image. Thus, I decided to repeat that step with a 4:3 screen.
I confirmed the need to press 7 often to save results since after I adjusted one grid color without it, I accidentally hit a key that switched me out of convergence mode and when I switched back, all settings were gone.
Another mistake I made was not realizing that the cursor color determines which grid gets moved.
Do these lines appear in a particular color like red/gree/blue or all? Please upload an image to http://imageshack.us/ After the upload completes, click on the image, click view full size, copy the link and paste it here so that I can have a look
any vertical or horizontal line (any color any size) showing stable on the screen that is the hardware damage at the LCD panel back board ( call panel driver board) . it repair complicate but easy to do change LCD panel (common parts). you need find a PC service dealer to do so.
