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

1 Answer

Samsung HCN4226W "image pinching"

After having the television on for a while (sometimes minutes, sometimes hours), the top and bottom of the picture will suddenly pinch in toward the middle and create an image with green and red ghost images, similar to looking at a 3D screen with no glasses

The convergence IC has gone out and is located on the Main bd or the Power supply bd depending on the specific model and must be replaced and a Full convergence alignment must be performed to return your tv to a watchable condition. Only a Samsung trained tech can do this.

SOMETIMES I CAN SEE A BLUE DOT ON SCREEN


Most manufacturers consider a few dud pixels to be normal and not a defect. Especially if not in the center of the picture.

Don't get fixated with watching the dot, look at the overall picture. It is like staring at a pimple on a pretty lady's chin.

How do I set my HCN4226W for 1080i?


I don't think the set will allow resizing in DVI mode, at least mine never has. I have to switch to the video input or S video to get that to work. I think there is something in the manual about that. On mine, the component input will not work if you have the DVI connected. If you have DTV, try resizing the image on the satellite receiver's remote. Sometimes, in the DVI mode, that works. I am about to pitch this set of mine out, as it now has fried something in the convergence system and won't work at all, so if the new convergence board I have ordered wont fix it, its going up on Ebay for parts !
