I bought a BDT-220 two weeks ago, have been pretty happy with it until yesterday it had a lot of flicker all of a sudden. I was watching Netflix at the time, so I thought it was a wireless streaming issue, and stopped watching the movie on Netflix, and switched to playing a video on external hard drive. to my surprise, the video has the same flicker. I turned off the 220 and turned it back on a few times, the problem still there. So I turned it off, thinking I might have got a defective unit. Hours later I tried again, this time the problem is gone. Anyone else experienced this? I bought it from Amazon so I think I still have a few days if it is defective and I need to return/exchange it.
