A universal remote "seems to" fix this issue. If you don't have a universal remote yet, try this fix and report back:
-I think foil would also work.
And just posted from an amazon reviewer that got a universal remote:
"HOWEVER, there are only a few small gripes that I have about this TV, but def. not big enough to change my star rating from 5-Stars.
The first thing you should do when you purchase this TV is to DESTROY the remote control that it comes with. Replace it with a universal remote or Harmony, etc., but the remote that the TV comes with is a piece of crap. I say this, because the remote has to be directly pointed at the sensor of the TV (which is located on the far left, in order to control the volume, power, menu, etc. Depending on where I sit on the couch, I had to sometime contort my arms so the Remote signal can reach the TV. I thought that maybe it was the batteries, so I replaced them with brand new batteries, but the same issues came about. I was then afraid it was TV itself that caused this, and not the remote, so I went to Best Buy to pick up a $15 universal remote control, and guess what?.....The problem disappeared!! Once again, $15 dollars from Best Buy fixed my problem..haha!! I loved some of the buttons that the 'original' remote had, such as the 'Netflix' and 'Hulu' direct buttons, so I just used the learning function on the universal remote to learn those Netflix/Hulu buttons. Now I can point my remote anywhere, and the TV will respond to it."
Let us know how you make out.
