Let me start at the beginning---Likely a bad main board in your case but nothing is sure in this type of set.

Main board controls all information to the front screen and communicates to various boards---There really is almost never a simple "that part is bad solution" as any board, the power supply, the main, etc can cause issues.

It can even be a issue with the front screen unit--called a display panel.

You might consider doing some research on the set by Google of the model number with "parts" to get an idea what is available and what potential parts cost might be.

If a main board is bad it will average from one to two hundred just for the part----if issue is the panel you are done--part if even available is more than set cost when new.

Let me know if you have questions.

SOURCE: vertical flickering color lines instead of pictures

Soory man there is no deflection yoke or vertical output IC in a plasma TV set.LOL This person has a problem with whats called the substain power supply or bad caoacitors in the main supply. there is also a possibility that the set has a bad tuner. Only performing test on the set will determine the problem.

I talked to a Samsung support helpline and it needs to be taken to a service center for repair.
