I have some problems with my Samsung 32in LCD TV, the picture will gone for a while if i turn on or off the switches on my home especially celling fan and lights. I thought it was my TV has some defect or something, but when i switch to tv mode and composite input and there is no problems but if i switch to component source the picture will keep flashing or like on and off it self and the backlight still lit but only the picture is gone for like 1-2 secs, and it back on and if you continue switch on and off the switch and picture will gone again and back on until you stop switching the switch but not all switch will cause my tv like this. please tell me what going on and is the component cable caused this or something, becasue it happen only on component source...
