After watching for a little while the color on the screen just turns to black and white. If you turn the TV off then back on again the color is back. We have had it against the wall and I now realize this TV needs to be a few inches away because it needs room for air to circulate so it wont get too hot. A friend told me that putting some compound between the metal and TK chips should fix the problem. Anyone have thoughts on this? Also, can someone please explain to me how I can do this myself?
