Again, other 940D owners have seen the picture I posted from Concussion and no one has experienced anything like that with their display.
You say you "would have returned the set within my window for an issue such as that." The thing is I didn't notice it for at least a month after the purchase. Why? Because I didn't start watching letter-boxed movies for a good month after I received it (I was traveling on business and we were on a vacation), and even then it didn't become really bothersome until I purchased my Philips UHD Blu-ray player six weeks after delivery (UHD Blu-rays, with HDR, manifest the light leakage much more than non:UHD material). So, I was way outside the window of return at that time.
I DID pay with a credit card, so what are my options having used a credit card?
