Fog and Sound cut out on LN40A630

This is about the open box 40A630 I asked about in terms of warranty a couple of weeks ago. Two things about it have me puzzled. First, if the AVS calibration forum for 630 models is any indication, a lot of people are using Movie mode for all around viewing, including cable/satellite HDTV. The strange thing with this set is that Movie mode presents a foggy image, no matter what other setting adjustments I make, and I've tried quite a few. Standard mode is required for good viewing with this one. The second thing is that every so often the sound cuts out during programs for 1-3 seconds. This didn't happen with previous HDTVs and the same Pace cable box. I'm not sure what to make of these, tho I can't help but wonder if they aren't related to why this set was previously returned.

Do these sound like anomalies?

genegold,

The first may be a preference setting that doesn't necessarily appeal to you. I'm not sure by "foggy" if you mean the picture is too dark, or if it's blurry. But the settings on some forums are just that - what some users think is best.

As for the audio dropping out, it's hard to pinpoint the exact cause. It could be anything from the television itself to an HDMI handshake issue or the cable box's level of sensitivity when connected to the cable box. If you're concerned, I'd see if you could have service come check out both the picture quality and the audio issue - perhaps resolve both of those issues at the same time, if they are related to the television.

Keep me posted!

Of the two problems in early March, the only one that continues is sound drop and that's definitely a cable company issue regionally (the repairmen also experience it miles away). Getting rid of the "fog" was a matter of finding the right combination of settings, which turn out to be similar to those of other users with the same 'S' panel designation as mine. The picture is excellent now.

At the same time, I *sometimes* (minority of the time) get a single pop or crack from the LCD's speakers when changing channels or exiting the panel's system setup. This is with HDMI. I know from both this forum and another for Samsung LNxxA630 users that I'm not the only one experiencing this; there's even a whole thread over at AVS devoted to this happening with an earlier Sharp TV LCD on a DirecTV satellite signal box.

I see three obvious possibile sources: the cable box/signal, the way the Samsung's HDMI board is handling HDMI signals, or the HDMI signal itself. I replaced the cable box with another of the same model, but that didn't solve it. I haven't tried composite cables yet, but that would at best only eliminate the third possibility and ultimately beg the issue. Any thoughts?

genegold,

A very thorough and logical reasoning in play here.

I don't have anything to add as far as what could be causing it. Did anyone ever conclusively figure out why the other brand was having the same issue?

No. Lots of different people testing the variables with different outcomes.

genegold,

I wish I had something a little more conclusive, but I don't.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
