I've recently purchased this TV, 42" Samsung HLR ,and it's been about 3 weeks now. I recently noticed that when I switch on the TV, the screen is very reddish, seems like it couldn't produce blue and green, even though I switch the channel, the picture just shows the color red, in different levels, the whole picture is very reddish. I have to switch off the tv, wait a bit and switch back on again then it'll be back to normal. This doesn't happen everytime, but happened just enough to worries me a lot. This could be an indication of larger problem in the future right? Any ideas?? Thank you.
