Well, I figured what the hell and decided to call LG on the banding. I spoke with the customer rep last week Wed, explained my banding problem, and he set up an appointment with the LG tech for Monday.
So the LG tech shows up in the LG van, very nice guy. After explaining and showing him the setup's inner grey fields in which you can see the LED-zone-induced irregularities, the guy says that's normal since these TVs use t up tolightbulbs behind the panel ...
. But he'll set it up to have somebody else come over, just call cust support to set it up and gives me a case #.
I call cust support, explain the situation, so he call dispatch to get the full story. He comes back with the tech having reported there's nothing worong with the TV set
. I explain again what he told me about sending somebody, and the rep is understandably confused, since the tech's report just says the set's OK.
I ask the guy if I can send him a picture of what my OK set looks like, and send him the gray field JPEG with the banding I posted earlier in this thread and puts me on hold while he receives it. He gets back on the phone and tells me, he's definitely sending somebody else to check the set
. He puts all these comments on the case, and includes the JPEG for the record. He sets up an appointment with a nearby authorized repair shop for yesterday.
Yesterday the non-LG tech comes. From our chat the chap seems to know his TV tech, and is a very nice guy. He looks at the grey field, looks at some anime scenes with vertical panning, and 10 minutes later was hauling the TV minus the stand to the shop to replace the panel. He said it might take a week.
So no TV for a week or so, I hope no longer! Let's see where this goes, but I'm hopefull ...
