Hello Everyone I have a Samsung LCD TV LE40B750. When I turn the TV on the picture is flickering for about 4 to 6 minutes and then it becomes ok. I have free sat and I have tried watching DVD to see if there is any problem with the set top box, but there was no difference. For the first few minutes the TV flickers regardless of what I am watching. Can anyone help me to understand the problem? And any idea how much it may cost to get it fixed somewhere reliable?
