Question about Samsung LN46A650 46 in. LCD HDTV
I have a flickering/flashing issue that seems to only appear on HD channels. It can be very prevalent at times but is usually only an occaisional issue, flickering once every several minutes or so. Could it be the cable wiring or the DVR box or something else? What is the best way to narrow down exactly what the cause is?

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.

Unfortunately if you chose to view the non HD channels in wide screen format, you are going to have the top and bottom of the screen cut off. Eventually this will not be a problem when everything goes to digital. However presently non HD channels are presented in 3:2 ratio where as HD is 16:9, So your choice really is to view them with the lines on either side for now.
I do not have an answer for the white flickering lines.
To get the BEST picture out of your 1080p unit I highly recommend using HDMI cables to hook it up.
I hope some of this helps.
Go Ahead. Use Us.

When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.

I had the power board capacitors on my Samsung 46LNA650 checked, and the out-of spec/leaking ones (13 in all) replaced. The horizontal lines disappeared; but, the left side of the panel was dark for about 20 minutes (until warmed-up). I then found this forum/link that solved the problem! This simple fix was probably all that was ever needed - IT WORKS!!!!!!
My Samsung now has a perfect picture again.

Have you check with the cable company to make sure they are broadcasting to you in HD ?
It takes more bandwith so some cable companies will charge extra for it so you will have to check.
