I've bought a Samsung PS50C550 about a year ago. And I have some concerns, i've done my research online reading tons of forums and articles but oppinions and advice vary to much it's only confusing...
- Image Retention
From the time I turned on the plasma, I've had problems with image retention, I calibrated the settings low during the advised break-in period and hoped it would go away, but sadly it doesn't.
When the TV has been on for a few hours and there is something static displayed (e.g. a channel logo or the media play homescreen), it will only take a few minutes and after that I have image retention... It will go away after an hour or so... If I turn off the screen with image retention still there and turn it on the next day, it's still there... it will only go away when dynamic content is displayed. All the burn-in protection features are enabled.
Today I was adjusting some calibration settings, not sure if some setting caused this, or it's always been there but I just noticed it for the first time... anyway, I have massive green/red/blue dithering, especially in the black area's. I read somewhere that turning down the brightness will help hide it, and that worked, when the brightness is under 34 the dithering in the black area's will fanish. When it's at 35 it suddenly appears all over the black area's, it will get more extreme when turning the brightness up.
After the break-in period, the calibration has always been set to the value's recommended in the review found on this website. In this review the brightness value is set at 50ish, but on my plasma that shows massive and massive dithering, it's easier to see when i'm up close then when i'm sitting on my couch but it's still visible enough to be annoying as hell.
Please some advice, it all this normal? Should I call Samsung to send someone over to have my plasma fixed? I would like to know the answer to these questions before my support runs out :-)
