Flat Screen TV Has Lines Going Through Screen - Possible ...

Screen-shots to defective LCD panels are given. You can see and compare to that to your device, and can make sure about the fault to an extent.

If you have parallel horizontal black lines on a white background, you can see the separation between the lines when it is viewed at close range (Figure 1). As you view the lines from further and further away,the image gets smaller, you eventually get to the point where you can no longer see the separation between the lines, and it looks like one line. Losing the ability to see separation in the lines is exactly what happens when you sit too far back from an HDTV set. If we apply the same principle to an HDTV, a 1080p resolution HDTV has to fit 1920 vertical and 1080 and horizontal black lines separated by the white space on the screen, (that is the pixel grid of a 1080p HDTV display). Furthermore the spaces between each cell of the grid need to be very small in relation to the area each cell occupies, or you will get a screen door type effect. A bigger HDTV can increase the size of the cells and the separation between the cells, so everything doesn't run together when you sit further back.

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.

More than likely you will need to replace the display screen. Those lines are a symptom of the LCD screen going bad. If you are still under warranty, see if you can get it replaced

If not, a new LCD screen runs about 15 dollars shipped from eBay and is pretty easy to replace.

Check out the following link for instructions on replacing the LCD display and links to buy the screen.

The only solution is to replace this top screen.

There are two display modes newly added for the DiMAGE 7i, grid and scale. The grid mode is to show a grid over the entire screen. This makes it easy to align the camera to objects vertically or horizontally. In the scale display mode, horizontal and vertical lines cross at the image center to divide the view to four sections, and each axis is scaled. This function is useful for close-up photography. The grid or scale on display is not recorded.
