Well, right place and topic but wrong equipment...;
I've got a Samsung 50" plasma,, but,, exact same behaviour as stated in this topic.
Im going completly mad with this. I started chasing Samsung in January,, nothing.
Recently,, in the beginning of August,, a supportincident actually took place.
1st after approx a week, a guy came out, took the tv down, just to find that he had the wrong spare parts with him.
2nd time,, I was sitting at home waiting for them to come and pick the TV up for inhouse service..,, When the day was nearly ending ( a workday...) I called them and asked if they were coming soon...,, Reply,, oh..sorry,, can we book a new day..??
Anyway,, now it's step3 ,, they have pick the TV up, they have had it inhouse for approx 14 days and,, I just got it back again...with the EXACT same problem.
Dancing red-dots all over on the darker parts.
But,, here's some strange info/observations;
1. using DVD and/or Sat-box,, this problem does not occur.
2. using PS3,, it occurs badly and..here's the strange part, after using PS3
the error will also occur on DVD.
I've tested with different HDMI cables (named and nonamed..)
I've tested through HDMI switch and without HDMI switch.
Another strange thing happening is that the TV seems to "reboot" briefly 5-10 times a day when watching films/tv/etc. This "feels" like its occuring more if it's HD content.
This "reboot" is very brief,, 1-2 sec's.
Anyway,,, How to sort this out ??,,, Samsung can say that the error only occurs
IF Im using the PS3
(but If I do,, the red dots are even there with the built-in screensaver for the samsung)
Sony on the other hand can state the opposite;
I can use the PS3 to my LCD Tv with this problem...(which in fact also is a Samsung..)
I know one thing...,, Im going mad..
