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.

Hi, i have instruction on removing your base stand.

Removing the Pedestal Stand
1) Carefully lay the front of the unit face down on a flat,
cushioned surface such as a quilt or blanket. Leave the stand
protruding over the edge of the surface.
Note: Extreme care should always be used when removing
the pedestal stand to avoid damage to the LCD panel.
2) Remove the jack pack cover on the back of the TV to expose
the pedestal stand screws. The jack pack cover can be removed
without tools.
3) Remove the four screws shown in the diagram below. This will
allow removal of the pedestal stand.
4) Once you have removed all four screws holding the pedestal
stand in place, remove the pedestal stand from the TV by
sliding the pedestal stand away from the TV.
