Sorry It's taken so long

Here are before and after pics, for when spots moved.

sweetibiza,

I've never seen that before, but I can certainly appreciate where you might consider that disruptive.

Does that happen on every input, or just the one where you're watching TV?

If it's just the one input where you're watching TV, have you tried resetting the cable/sat box?

It happens on every input. Wii, PS3, Sky, Cable box, Media player, so a screen problem...the mystery is that that as you can see the dots have moved and where they were the picture is ok and in one position another dot started forming and growing!

sweetibiza,

Well, it's not often that I say "I've never seen that" on the boards - I usually get to see a little bit of everything. I have no idea what the problem might be. But if the symptom is that the black circles are moving, and the places where the spots used to be are displaying okay, it may be an issue with one of the electronic boards behind the panel and not the panel itself. Considering the cost of a replacement panel can be pretty high, this is actually news that works in your favor.

Now while this is far from being any sort of actual diagnosis, it may indicate how you might proceed. I'd recommend calling the Samsung customer service center in your area to have your unit inspected. Unfortunately, there's no troubleshooting tips that I can offer.

There is one, actually. I might try resetting the unit by, with the TV powered ON, press and hold the EXIT button on the remote for 15 seconds to see if you're prompted with an option to, "RESET?" If so, press YES and you'll be prompted to go back through the initial factory set up. I have no idea if this would work or not, but it may be worth trying prior to calling and having a service set up. That's the best I can offer.

SO...My sanity is intact!!! At least I have baffled the expert!

I did do the reset and this did not do anything. I don't know how LCD's work, but it's like there is no picture colour being able to be displayed in those areas so the lights blend to make the black colour. Even stranger is that when the TV is off you can actually see the circles on the screen like screen burn, but again where the spots have moved there are no shadows or typically screen burn!

I've only had the TV for 3 yrs and have had the TV power 'clicky' fault, then a speaker fault..all of which were capacitor related. The TV is out of it's 1 yr warranty and so no free call out. I have to pay out for an engineer now to fix a TV where I'll have to pay parts for that I could fix myself as they probably won't know what is wrong either.

sweetibiza,

Well, I can't assist with non-US products, unfortunately.

But try calling them and explaining that the LCD shows the symptom even when it's off. They may still deny a one-time service - and technically, they can - but it's worth trying.

Let's continue with the one from 2011.
