IMAGE RETENTION ON SAMSUNG PS50C7000

Have you calibrated the screen? Leaving it on default settings will almost certainly make things worse as contrast will be too high
hi i have settings on dymamic with contrast set at 80 is that to high also cell light at 15 and brightness at 45
Dynamic is completely wrong for a calibrated (calibration means things look as they should) picture. And will certainly be contributing to your problem.

Turn off the dynamic mode and calibrate the screen properly as excessive contrast and brightness will make this problem far worse than it should be! Also keeping the tv in dynamic and not calibrating the screen will considerably shorten the life of any plasma screen, you will do the most damage to a plasma screen in the first 2-300 hours of viewing so proper calibration is absolutely essential and if you are getting IR this soon into the tv's life then there is a danger you could end up with images burnt into the screen although this is rare but it did happen to me so be warned!
Plasma is very different to LCD and calibration is essential to the life of your tv, also you should recalibrate every 6months as the black levels are subject to change over the life of the tv. For the sake of a few minutes with a calibration disc it really is worth it.
If you have no dvd's with THX optimiser on them do a google search and you will find plenty of alternatives out there and many free downloads that will do the same job.
Don't worry too much about IR at this point in the tv's life as it's to be expected to some degree untill the tv calms down a little as the plasma cells are at their most excitable for the fist 2-300hrs viewing.

hi nick thanks again for your valuable input into plasma i have taken it of dynamic and now in standard done a bit of adjusting picture seems to be better you say that plasmas need to settle down as the cells are more excitable for the first 2-300h does this mean that the picture will inprove over time ie blacks getting blacker etc which meaning adjusting picture every 6 months or so regards andrew

Andrew,
Exactly! The first 2-300 hours are crucial to a plasma tv as the cells behave differently up to this point, a bit like an over excited child is the best way to describe it. As the screen gets more use then they start to settle down and this is why it needs recalibrating to take this effect into account, you are right that black levels and contrast will change over time simply because of the cells settling down and thus recalibrating is needed. After the first year they should have settled down to a consistent level and thus recalibration shouldn't be so much of an issue and needed perhaps once a year just to make sure that the levels haven't fluctuated.
Hope that is of some help to you and that you are still happy with your purchase? I saw your other thread about the picture blanking out and was going to reply to that aswell as i thought that was the now infamous sky box issue some people have had, did you solve the issue in the end? Didn't see the point in posting that comment on the other thread whilst i was writing this reply on this one.
Best regards
Nick.

hi nick been in touch with comet service centre as the tv was switching its self on and of intemitly gave them software version they said it needs the latest version so they are sending it out to me on a usb stick they said this should solve the glitches that i am having at the moment, so the blanking of the screen is a sky box issue then anyway of stopping it happening maybe changing the resolution output to auto on the sky box ? im happy with the tv just get these niggles sorted out and yes a bit dissapointed with the black levels a bit misty grey but as you said once tv settles down should be alright i will keep you posted as to if the software upgrade solves the issues with the tv at the moment regards andrew

Well from that description i would say that the sky box isn't the issue. The sky box issue happens when you go from sd to hd content or vice versa, the screen goes blank for about 3-5secs but doesn't switch on and off as you described, are you sure that the tv is actually powering down by itself? Does it go into standby for example and then start up as if you had just turned on the tv?
That's good service from Comet as not many retailers would send out the updated software on a usb stick but just out of interest is that not something you could do yourself? My tv automatically tells me of updates that are available over the internet and downloads them to the tv or is this an issue with your internet connection...i presume you have the tv connected?
It does sound like the sort of niggle an update would solve though so either way i hope it sees an end to the issue.
EDIT: The misty grey blacks can be caused by 2 factors. 1, during the day and in a bright room you will find that the blacks can turn a shade of grey but closing the curtains is an instant solution and 2, calibration can irradicate the problem as the brightness and contrast need to be just right to get the deep blacks.

hi nick when watching tv it just goes into standby and stays in standby until you switch it back on or if in standby it can switch itself on its only intermittent at the moment i have got a samsung dongle connected but its telling me no latest software available hence why they are sending the latest as there is one available they said this should solve the niggles that i am experiencing evidently samsung tvs are prone to little glitches if they dont have the latest software so hopefully this will solve it fingers crossed eh!

Andrew,
Definately not the sky box issue then! That is a glitch with the tv for sure but it's very strange that the tv doesn't pick up the update that comet say is available, have you checked the Samsung UK website to check for yourself that an update is available? You can view and download any updates from their site and update the tv yourself without having to wait for comet, the only reason i suggest it is that if the update doesn't solve your issue you can return the tv pronto and get it replaced as you will be within the first 28 days of purchase and get no hassle ie having it sent away for repair, i'm sure you don't want to go through that again eh!
I truly hope that the update solves the issue so keep me posted what happens if you can

hi nick yes done the update myself there was one available on samsung website so dont know why my samsung dident pick it up anyway i will see how the tv is now fingers crossed it will be okay i will keep you posted regards andrew
Contrast setting should be set to "normal". Dynamic contract at 80 is the cource of your problems - and will be the cource of your future problems ( apart from you kill the gray scale ). Contrast should be around 60.
Plasma have no backlight - the only way to get more light is to fire up on the plasma cells --> high power consumption, -->image rentention, --> extensive heat --> shorther lifte time.
If a normal contrast setting is too dimm for you - or contrast is washed out during daylight - you baught the wrong TV technology.

Hi Andrew,
Hmmmm doesn't sound right to me!! You should not need to do this every time you use the tv but the fact that such a feature is included on the tv may point to this being a common issue, have you googled it? Of course you have to remember that people are more likely to post negative opinions than positive but it must be a good place to start....then i would contact Samsung to get their opinion on the issue but don't forget i had image retention/burn issues with my 42g20 and it is a known issue with plasma but i would still say that it doesn't sound right that you should have to use the scrolling function every night. To get that much IR is not good but it may yet settle down, if it were me i would be making a call to Samsung to get their opinion as it doesn't sound good to me and don't forget i had IR issues/burn with my 1st 42g20 so some sets can still suffer!
One question, if you don't use the scrolling function what images are left on the tv? Is it just things like tv channel logo's in the corner of the screen or is it more general such as any still image? Oh and have you had any instances of an image that has been hard to budge? I only ask because it could be a refresh problem and not IR which was the problem with my 1st 42g20
