Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

My samsung hcn4226wx rear projection tv

I have two major problems with the picture quality. There are tiny purple and red zig zag lines on the screen which appeared first for a while followed by horizontal lines or shadows that seem to be created from text or lines from various graphics within programs and alter position when the screen changes. Would replacing the main board solve these problems?

If the lines are moving....look zig zag - etc...your hypermodule has likely gone out. You can get a repair kit from www.TvRepairKits.com

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

Distorted picture


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
