Is this happening on the Tuner input? If so, low signal strength on reception. Add amp to antenna

Hello luckyone1,
According to your name you get one lucky fix..not two

OK, OK ...That was funny
What do you meant by zigzag line? Do they look like what we would call herring bone. lines going sideways? Please let me know. If this is the case, I have never been able to solve that problem. I am very close with the tech over there at Samsung. We spent hours on this problem. We changed Complete main board. We also changed Power supply. The problem maybe coming off the Yoke or a somewhat defective picture tube.

Please post reply if someone did correct such problem

Best regards

to tell which board you have there should be writing on the corner of the board in white.

sounds like your screen controls are too high? thay are behind the front cover 6 contols 3 for focus and 3 are screen the screen controls.

when you say distorded, is it like a 3-d effect? or more of zig zag type lines in the picture. If there are color outlines like a 3-d effect, then you are having a convergence preakdown, and are going to need to have the convergence IC's replaced. if the problem is the piture is zagged edges and zig zag, lines or a smearing effect, most likly it is the PIP modle is going bad, and even if you dont use the PIP, the video still goes through that module. If it does not have a PIP feature, then there are bad capacitors in the sweep power supply and the problem will get progessivly worse till the set wont come on anymore. Hope this helps. Good Luck

Are those lines all the way up/down your set? Or just in small zig-zags?
