These two images appear seperate from each other. One is aprox 10in from the right side and the other almost center. Both apear to look like a water mark of sorts, not much more than 2in wide and vertical through the screen. The intensity of these images varies with the back ground screen picture colors. Dark background; highly visible, light background barley seen.
I have the same issue. A have a band down on the far right and a second about 4 inches to its left. I don't ever really remember noticing it until recently. Appears like dust or dirt on the inside of the screen. Is there a cleaning method?

Check and replace its LVDS cable [the cable that connects its T'Con board to panel]. Re-seat it once and check, before replace it. Any loose contact with either side of this cable; or the cable itself is damaged, can cause this fault.If you wish to get some details, check the site linked here. Pull up older posts.
Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards. An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time. Since you haven't told us the exact model i can't point you to a replacement board.
Hello; I am John at J. D. Electronics, Poland Maine. This problem is caused by a defective LCD panel. This part is very expensive! Aprox $ 1000.00 from Sanyo and less than $400.00 from Encompass Parts Inc.
the problem here is the Lcd controler or T-con board. The problem is Toshiba does not alway sell the board seperately you may have to buy the complete LCD panel Call toshiba Tech support or check on their web site for you particular model
You have a bad optic block assembly. This is a common failure on these TV's and has to be replaced by a technian. The part number is UX25307 and costs about $620.00 dollars. If you don't have a warranty you will probably be bst replacing the TV as parts and labor will probably exceed $850.00
50V500 ONLY GHOST: May be described as "Out of Convergence" but ghost is still attached to main image. CONDITION: A "ghost image" appearing to the left or right of images in the picture.Can be varying shades of a primary color (red, green, or blue) as well as gray.Can easily be seen in the 4 x 3 mode, at the edges of the picture. CORRECTION:
To correct the problem, please do as follows:
Access I2C Menu. (See page 57 of the Service Manual).
To enter the I2C Service Menu, with power off, (on the front control panel) press and hold the INPUT button. Then press the POWER button for two seconds. The following Service Menu will appear.
BEFORE CONTINUING: CONFIRM THAT THE R, G and B DRIVE ARE SET AT 40.
Be sure to press SELECT after each change to SAVE the new Data.
Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
Move the joy stick to the right to cursor right once.The next page will appear with the word GHOST highlighted.
Cursor right again, and a white screen will appear with a BLACK SQUARE in the center, as in Figure 3.You will see LCD ADJUST, followed by “SHP” and a number (value).
If the unit is out of adjustment, you will see a gray ghost on either side of the black square. Move the joystick to the right or to the left until the ghost disappears. The number values will change up or down.
If the ghost adjustment is off with a lower value, there will be a ghost to the left of the square.
If the ghost adjustment is off with a higher value, there will be a ghost to the right of the square.
Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
Press the "EXIT" button three times to return to normal picture.
If it's still under warranty call 800-243-0000 (LG customer service) and get them to send a technician out from a different shop. After 3 (or maybe it's on the 4th) repair attempts if it's not fixed you can ask for a different TV.
