Well FINALLY have my TV back in a working condition. Initially returned 10 days ago with a damaged stand so had to go back a 2nd time. Returned again this afternoon.
I can report that as suspected there must have been a pre-existing issue with the unit. Interestingly, when I first got the TV my chosen settings were always substantially lower than most users on these forums had theirs. Cell light was 12 for me, compared to 16 - 20 for most users. Contrast was again set relatively low for me and so on.
Having turned on the TV earlier I was dismayed at what appeared to be a washed out lifeless picture particularly as none of my settings had been changed. Referring back to suggested user levels I ramped up all the settings and - fantastic vivid picture. No red misting or blemishes to be seen. I do think the black levels are slightly greyer than previously but I can live with this. No brightness pops either!!
Do you think they may have replaced the panel or would this not be the case given my earlier settings were intact? I ask because I would prefer to run the unit in again for a couple of hundred hours if this was a possibility.

Quite possible there was an underlying issue with the unit. Ah well. As stated earlier the electronics retailer have their own aftercare service so Samsung won't factor into the equation. TV is being picked up Monday. Support centre logged the fault as potential panel failure due to the sudden appearance of 'clusters of red dots'
