I believe you. I got my 50ST60 today, and I had faint but clearly visible IR after exploring the menu for a measly 5 minutes in Cinema mode. It consisted of the "Viera Menu" text in the upper left corner and settings rectangles beneath it when viewing (for example) a 20% gray image or pure white screen. It cleared up after 15 minutes or so of the Screen Wipe. Later experimentation reproduced the IR creation and confirmed that slides also clear it up.
The set also buzzes badly as APL increases. I've never had a plasma, and I'm shocked at how loud it is. It's easily audible over quiet dialogue plus some minor AVR transformer hum and PC idle noise (albeit a very quiet PC) from 11 feet, which is as far as I can get from it in my room. It's really fun to watch scenes with flickering bright lights; it's bzzzzz-shhhhh-bzzz-shhh-bzzzz and on and on.
I would say the amount of IR I had would have no effect on normal viewing, but I have no idea how bad it can get or how persistent it can be. I have a very good LCD monitor (NEC 20WMGX2) that is susceptible to similar amounts of IR, and it has never been a real problem, just something I notice every now and then when a particular background color overlays an affected area. It's actually a replacement for another 20WMGX2 that had insane amounts of quickly acquired and very slow to dissipate IR; I would not say the ST60 is anything like that.
I'm pleased with some basic picture settings so plan on just watching the ST60 and running slides for the next 100 hours, and while watching shows, I'll also get a better idea of how intrusive the buzzing really is in practice. If it turns out to be a problem, would it be better to contact Panasonic or just exchange the set? I hate to exchange it, because I see no pixel defects, banding, DSE, or other problems. It's just the buzzing and the IR. Why can't I buy a perfect TV?
Oh, and the buzzing essentially goes away in Standard mode thanks mostly to CATS and to a far lesser extent, the default contrast of 50, which is pretty much unwatchable even in my dark room, unfortunately. I haven't found any usable setting combination that can mitigate it.
