Sylvania 6842, bars in picture

This unit has constant vertical lines or bars in the picture from top to bottom about an inch wide. Is this likely to be a sustain driver module, or could it be the display itself?

The service manual troubleshooting procedure says to replace the control circuit board and if that doesnt fix it to replace the display panel.

The screen has colored vertical lines and becomes to a dark black band about 6 inches of width.The tv is exactly two years old by today.


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (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 solution updates will be on my Facebook page.

Black vertical line about 3 inches wide from top to bottom on rig


See if you can center the picture in the setup menu. It sounds like it's just off center.

It sounds like your vertical has shrunk, causing the picture to look squashed. Most likely a bad component in the vertical output stage.

Sylvania SRPD442: picture has lines and particles in it, can't make picture out


The fault can be the screen itself, or one of the driver boards for the screen. This has to be verified by trying the boards.

I don't know for your model if the backplane lamps can be replaced. In most of the models they can be.

Too late now but I hope you had it serviced while it was still on parts warranty. With a couple of exceptions, service on those is by major pcb replacement.

The picture is too large for the screen


If you have a cable or satellite HD box see if there is a ASPECT button or look for an aspect/picture size buttn on your TV's remote control.
