You seem to have what is called error diffusion. Either call samsung about it and arange service or do it on samsung.com. What kind of warranty do you have? Depending on your date of purchase you might be able to get samsung to help cover it or pay for it all.

i will first resolder all ic`s and connections,especiall on the crt board,clean around the flyback at the abl circuits,check for open or changed valued resisters in abl circuit and the video b+ on the crt board (usually 165-200 volts) check also the screen voltage (G2) volts,should be around 250 - 400 volts.

It is due to the power regulator section of your TV. If DC voltage come to T'con board and other circuit board won't have enogh regulated and smoothed current this type of fault will occur. Open your Tv and check for any bulged capacitors on the mains power regulator board. If there, repalce it with same type and capacity. I hereby attaches a picture, of an other set's power supply board with bulged capacitors to give you an idea about how a damaged and bulged capacitor will look like. Check this, If you want anymore assistance from me, feel free to get me by Fixya.
Note the top of the red arrow marked capacitors. They are damaged. A ggod one will look like one you can see on the top right with flat top surface.

Same here. TV back-light would flicker occasionally. Sometimes it would stop and other times it would not. This is the only TV I purchased with a warranty (because I bought it online and got a great deal). The Samsung repairman came out and changed out the circuit board that has the power supplies for the back-light. Total time was 10 minutes to fix. Apparently this is a known problem with some of their TV's. He said the vendor for the power supply transformers had issues and they have since changed vendors. The flickering is caused by one of the transformers failing (it has 2 to power the back-light).
*NOTE: even if your TV is not under warranty call Samsung directly. They should still do the repair for free according to the repairman. Just tell them that you have seen postings on the internet about this problem.
