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

3 Answers

Screen Voltage I am getting random, faint, pencil lines, as well as thick shadows that stretch across the screen like when there is white lettering and a dark background (terrible description, I know). I have been told this has to do with the Screen Voltage. When I take the front cover off there is the black box on the front where you can adjust the colors and I was told you can adjust the voltage there to but there are no knobs to turn. Where else would they be. This is a Samsung HCN4226W.

    I have this same problem. Did you adjust the screen voltage to get it resolved? How did you get the fron cover off. it almost looks like you have to loosen up the rear cover for the front to come off.

Yea that is. The focus is the bottom three and the screen is the top three. Its looks like there is no way to turn the three screen ones. Also does adjusting the screen voltage sound like its the fix to my issue?

There are two reasons for this fault. A fault smoothing capacitor at the video output voltage rail, or excess of screen voltage. These lines are called 'vertical retrace lines' technically. Check this link for more details. It has a post, which have information regarding this fault. Go to older posts there.

My toshiba laptop has a thick white line down the screen


The normal cause of lines across the LCD of a laptop is a damaged video cable. The unusual cause would be the video card itself.

To determine which item is at fault, you need only attach an external monitor to your laptop's video-out, and then swap your monitor view to 'both' or mirrored (usually just the function key (FN), plus one of the Fkeys...look for an off-blue picture of a monitor on the Fkeys).

If the lines across the screen also appear on an external monitor, then the video card is damaged.

If the lines only appear on the laptop's LCD, but not the external monitor, then just the laptop's internal video cable is damaged.

Hope this helps.

Thin vertical line


What you have described is definitely some form of Electrical Interference. Interference can come from a variety of causes. Is the Cable Inputting the Cable Box close to some High Voltage Electrical Lines? Or Are you located near some Electrical Power Station? Or A Police station, where the Radio Transmitter of the Police Station causing the Interference? As I said, there are a variety of reasons. Also, Try to check if the connector is loose at the rear of the Cable Box, or at the rear of the TV. You will have to eliminate every possibility reason. Wish i could help further.
