Samsung PN43D450A2D, screen vertical line, flickering

[taeyang999]

Hello,
I have three years old samsung 43" plasma tv that was connected to my security system using RCA.
One day, I turn on the tv and it is showing like the picture I attached.
So far, I did factory reset, upgraded newest firmware. Nothing fixed.
I need help fixing my tv. I really appreciate for your help.

I would guess CTRL board needs replacing.

I would guess CTRL board needs replacing.

Do you know part# and where I can order?

Best to get the part number off the board itself. It's the small PCB in the lower middle of the screen below the power supply, will have ribbon cables connecting to the Y main (left side looking from the back) and the lower buffer boards, and one connecting to the main board (the one with the inputs on).

It's a guess but it looks like a classic CTRL board type failure.
