Read the thread. Did the test. Although its propably there, really cant see it. All three images. Oh well nothing I can do about it. Out of warranty. Save up for a different TV. Probably Vizio. Screw Samsung. Never again
Actually, there is a good reason to buy Samsung, at least some select sets. In these, Samsung offers a 5-year warrantee for free. If there is a problem, it would likely appear in these five years, I am sure.
No manufacturer is free of problems. By the way, purple spots have been known to appear in LG LED sets as well. It is not exclusive to Samsung. Other problems occur. For example, a Visio TV that I owned just died (dead as a dodo) one day after 4 years!!!
Thus, especially with lots of new technology, these extented 5-year warrantees are probably a must.
I also have the Purple Patch issue with my 5 year old Samsung UE50H6400, purchased from John Lewis Ltd. So I am outside of their 5 year warranty, but still within the 6 year claim period of Section 75 of the Consumer Credit Act. I called John Lewis to discuss my intention of pursuing a claim on this basis and they came back to me with the suggestion that if I paid the £105.00 call out charge for a Samsung engineer to confirm that my TV was “either inherently faulty or unrepairable”, then John Lewis would be able to settle my claim to the sum of £22.20.
