hmm, dont like the sounds of that. I've got until next sat for DOA replacement, so will see how it goes. I also got the extra 4yrs warranty for some extra piece of mind..

Felix, still on standard settings for now (which seem pretty good). Havent really had time to play as have been messing around with a new AV cabinet and transferring all my gear from the old theatre room into a new lounge room set-up. Got new cables on the way and will need to further modify the cabinet to deal with the overheating, so might be a little while yet before i can get to play around with settings.

just looking forward to it all being done so i can relax and enjoy it!

A pain it may be to take it back to the store, but I agree with Owen. I'd rather have a functioning set out of the box than one that has already exhibited signs of going to TV Heaven. If it were me, I'd take it back and get a replacement.

[Dissociative]

I think youre right and it may be better in the long run to do so. Spoke to the salesman briefly and he was happy to arrange replacement if I had any concerns. Would hate for it to pop up again in a months time and get stuck with a refurb..

In the car industry there are alot of intermitant problems caused by firmware issues. These are then fixed via revised firmware, i don't see why this couldn't be the same for a TV?

[jasoroony]

In the software industry there are lots of intermittent problems too, which could easily lead to corrupted system memory.  Making definitive statements like the one Owen made is just being silly.

Still, you never know - and I'd probably consider a replacement for that reason.

[Owen]

If it was a firmware issue every TV of that model would exhibit the same fault and that is clearly not the case here.
Never update firmware if there is the possibility of a hardware fault.
Only update firmware to address a recognised fault that the update is specifically intended to fix, otherwise you can end up with more problems then you started with.

Updating firmware without a very good reason is just plain dumb, especially with Samsung TV's.

Clearly.. another definitive response from Owen.

[Owen]

It seems implausible that the TV was fine one day and faulty the next with the same firmware and hardware, or why other TV's with the same hardware and firmware do not exhibit the fault.

There are other D8000 owners here but they have not reported this problem to my knowledge.

[jasoroony]

It could have been a particular video media file being played through the TV by Dissociative, setting something unexpected and permanent in the system memory.  Then not many people would experience it.

EDIT: I had an Intel video driver that would BSOD when a weird resolution video file was played...  Fixed by an updated driver.

Whatever the cause or solution may be I'd be pushing Samsung for a replacement panel regardless, even if it is bit of a hassle to arrange.

There are plenty of members who have purchased these 2011 models and this is the first I've read of anything like the symptoms that Dissociative was reporting.

It is possible that if the TV was being played with a bug could be triggered that would normally not occur, however a system reset would have returned the TV to its as delivered state and fix the problem without upgrading the firmware.

[jasoroony]

And... based on what Samsung told Dissociative, the new firmware will prevent it happening again, if the TV is played with the same way.

That is, in this case, the real fix.  At least from the scant details available here.

[Owen]

There is no evidence the fault Dissociative experienced is the one the firmware update supposedly addresses.

Dissociative, where you doing anything other than just watching TV, like playing with settings or using the media player?

And yet you rule it out, definitively.  Nice work.

[Dissociative]

i cant recall exactly what i was watching when i first noticed the issue, but from memory it was around the time i tried to watch an AVI from my apple tv. i say tried as the audio was all screwed up (as was the picture). i tried to watch the same AVI after the firmware update and it played completely fine. Perhaps that caused an issue?

prior to that, the only thing i had done with the TV was watch foxtel. i had not touched any features/settings, including the smart functions etc.

HDMI

i'm unsuccessfully trying to re-establish the arrangement that worked so well with my previous tv:
3 HDMI (pc, pvr, dvd) into receiver (yamaha RX-V3900), 1 HDMI out into tv. to switch sources you only have to switch receiver.
doesn't work with my new samsung: pc doesn't show at all, pvr ok with 1st channel, but when i change the whole screen turns purple. only dvd is ok.
the only option now is to connect the 3 components directly to the HDMI sockets on the tv. that works, but i have to change source on tv ( picture) plus on receiver (sound). what a pain.
rang support who suggested firmware upgrade.
any idea what could be wrong?

If the TV did not have a hardware fault a system reset would restore normal operation, a firmware update was not required nor advisable until the cause could be determined.

Good fault finding technique requires that you do not introduce new variables, I do it for a living.

What PVR do you have? Is the video output set to 'passthrough' or maybe 1080i? If it's set to passthrough, each time you change channel, the PVR sends through new resolution info to the TV, and therefore you need to resync HDMI. You could toggle the input on the AVR and this will get you the next channel, but IMO, just fix the resolution to say 1080i and see how that goes.
What resolution are you sending out of your PC? This could be incompatible with the TV, or your AVR could be introducing a problem with the signal. More info is required to see if we can sort it out.

It's not a FW issue IMO. Just need to rejig things a bit. Simplest solution would be to buy a Harmony Remote (or any other decent universal remote with macros) and let the remote do all the switching of inputs for you.

thanks for your reply.
after again wasting half a day getting pc and tv (direct HDMI connection) to shake hands i guess i just leave it with that, same with pvr (1080p out). will try to set up macros on remote instead of running components thru receiver.

btw, the picture quality is 100% better after calibrating according to cue's or tivo's data.

enjoy!

ok so I ended up getting the TV replaced and all has been fine, except for one thing - it buzzes.

I'm pretty sure the first TV did as well, but i was ignoring it. however, over time its really getting to me and i can hear it constantly.

any ideas? anyone else noticed this with their D8000 plasma?

Yep mines 2 weeks old and buzzes and has the brightness pops

[tolly84]

If you call Samsung about Buzzing, can they fix/repair it?

My wall mounted 64D8000 is ridiculously quiet @ 2.7m. I would've expected such a large plasma to have at least a slight buzz as my Pio Kuro had. But it's dead silent unless I get up to it less than a foot away. It does seems something that varies from panel to panel and no doubt the unique accoustics of the listening environment and the sensitivity of the listener also plays a role too.

How do you have it mounted and how far away are you sitting? Do you hear the buzz anywhere you position yourself in the room or is it more noticeable in the prime seating positions? Can others in your family hear the buzz? Is it more noticeable with bright scenes?

My Kuro definitely kicked the buzzing up a notch when displaying a bright white screen which was the only time I really noticed a buzz and only then when the audio was low during quiet passages of dialogue or similar. I've never heard a buzz from the D8000 at any stage in comparison.

You may be able to try accoustic tiles or some other treatment to deaden the sound reflections of your front wall behind the TV.

http://www.dtvforum....showtopic=23805

It does sound like it's something you will be unable to live with and probably unlikely to improve over time. So if you can't find a solution to effectively reduce/eliminate the buzz either another panel replacement or dare I say a swap out for a completely different model/brand maybe on the cards unfortunately. Of course competing products such as the Pannies have their own set of issues to deal with as well.

Gee you haven't had much luck with the D8000, first that bizarre video issue and now the buzzing. Such a shame as it's a superb TV imo.

thanks felix, yes definitely not a great run, but other than these niggles its a great tv and i can't think of anything else id rather get, so hopefully won't end up going down that path (although i do already wish it was bigger).  

the tv is wall mounted using the samsung ultra slim mount (so 1.5cm from the wall). slate floors and no soft furnishings unfortunately, so definitely not great acoustically. i sit 3.3m from the TV in the main seating position and its very noticable (its noticeable from all positions). I'm definitely more sensitive to it (now that I'm fully aware of it), but my wife can hear it too.

haven't noticed any trend or change with brightness etc, just seems to do it all the time.

i wonder if it could be anything related to power or interference? might play around with the ferrite cores (can't recall if i put them on) and see if that makes a difference.
