I would like to diagnose what part of the plasma display causes this problem, i have attached pictures below .
It is a vertical line on right side of the TV screen. below is a close up of the line (pictures)
Any help appreciated , thank you in advance.

I took off the back panel and i have noticed that a logic board has a blinking little green led on it , constantly is blinking on and off. i think it maybe a problem with the logic board

downunder:

The constant flashing LED on the logic board is normal on an operating Samsung plasma. You're looking at a faulty connector between the display panel and the buffer strips along the bottom of the panel, situated directly behind the vertical line. These connectors are fused into the panel glass at one end and probably glued to the pcb strip at the other end and may have a driver IC embedded onto the connector cable.
You may be able to effect a repair by using a pressure pad on the strip end if the fault is there, but all other scenarios mean the display panel is knackered. So, removed the metal strip that covers these connectors and check there.             Bruce
