Vertical Lines on Samsung TV

Hi, I have a Samsung 55inch TV UN55C6400RF. It has started showing colored vertical lines. I have opened the TV and the power board had one pin out1- which is discolored Model # bn44-00358b. Can this be bad or is it the T-Con board Model # D03464E0J09B6012066. Any recommendations on diagnosing the issue? Thanks, Sanjay

Test the voltage at the main to make sure you have the proper voltages from the power supply, if they look ok try a new timing board.

    Thanks Larry. Are there instructions or youtube video which I could look at to test out the voltage.

    look on the power supply board for connector 801 there will be a legend on the board telling what voltages are at what pins, test each using frame as ground.

My samsung LTF320AP08 television shows black screen and then coloured vertical lines . It has volume but no image of channel

When a TV is showing vertical colored lines, a loose wire cable in the TV might be the cause. If you knock on the back of the TV, the vertical colored lines MAY disappear temporarily. This is a sign that a cable is loose or the T-Con board is faulty.
A black screen could just be a sign that the TV is turned off, although if it is producing sound then you know that's not the case. When your TV has a black screen even when it's on, it's quite possible it could actually be your external device and not your TV.
