Hi,

Black vertical lines on your P42W34?

SOLUTION 1:
Apply pressure between the silver metal board and the orange ribbon cable on the bottom portion of the TV where the black lines occur.

SOLUTION 2:
(If soution 1 doesnt work)
Just reheat and add soder to fuse connected behing the driver boards.
It's an easy fix usaully takes a hour. Over time the connection from the soder on the driver board dries and seperate or loses value due to heat transference. Remove the back locate the driver boards they are rectangle like shaped alumiun slats that run across the bottom of the plasma. Underneath the slats you'll see four square like fuses with the number 100 imprinted. Purchase a sodering iron at Sear for $15 add a touch of soder to the ends of the fuse to re-establish the connection. Repeat process for all driver boards, make sure the unit is unplugged before you proceed. If it's fried replacing it is not a problem just resoder the new fuse to both ends to establish the rely.
ENJOY! RATE THIS SOLUTION

1" black vertical line in center of screen. Sony Plasma.


NOT DEFECTIVE!!!
There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable2_bing.gifnear the black lines. Unplug the ribbon cable and look for black chipson the underside of it, I think they say 100 on them, you need toresolder both ends on each chip. Should fix the black line issue.

Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use


I also have the same problem I phoned Samsung today to explain the tv was only 14 months old, they didn't wanna no because it was out of warrenty by 2 months. I am getting a black solid line down the left hand side of the screen. I ended up phoning Dixons were we bought it from, they have told me to get an independent engineers report done & send the report to them within 14 days. Dixon told me it was a known problem with Samsungs. They said they will fix it free of charge if they can if not they will send vouchers to the same value of the television. So beware stay clear of Samsungs.
