Samsung LN46A650 flickering issue on HD channels

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.

SOURCE: Picture issues

Greetings caesar975,

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.

Sincerely,

Dorothy

SOURCE: connecting HD cable box to DVR too HDTV

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.

SOURCE: 3 horizontal lines on Samsung LN46A650 upon start

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.

SOURCE: Can't get HD cable channels on Samsung TV

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.

Samsung LE40R71B flickering problem


appears other people are having the same issue with Samsung TV's.

Try calling Samsung or wherever you bought it from.

I've been dealing with Samsung on this issue.

We got a 40" LCD in October 2010 and it started flickering January 2012.

Changing it from 'standard' to 'movie' helped (natural and dynamic flicker)

Then it started flickering in 'movie.'

I called Samsung and told them this issue is all over the internet. They agreed to pay for repair, parts and labor, even though it's out of warranty.

The guy just left and this is what I know. He said that in the 46" and larger, the issue is a jumper. In the 40" and, I think, smaller, it's the panel. He's ordering the panel and will be back to replace it when it comes in from the warehouse in CA.

Try calling Samsung and good luck!

Samsung le40f71bx picture flickers on and off with hd source


I've had similar for a long time, now the picture only lasts a few minutes or seconds. Have to turn the TV off, wait 5 minutes, turn it back on. That's with Sky HD. Used to be the same with SCART but I don't use that any more, and I get it with the Wii on Component. However HD DVD and Blu Ray players are no problem!

See my post here - http://www.avforums.com/forums/lcd-led-lcd-tvs/1622157-samsung-f71-flashing-pattern-fault.html

Way out of warranty but really just need some repair expert to tell me what needs fixing. Taking the cover off there are very few components and look easy to replace, and seen some on ebay. A fix from Samsung would be vastly in excess of the value of the TV.

Sound cuts out


This sounds to me as an issue not with your AVR but with your cable unit. I have seen this where there is a sample rate issue with the cable boxes. I would try to get another cable box, and see if the issue persists.
