I got this set a while back on clearance at the local Best Buy and I was wondering if anyone else has experienced this problem? My set used to take about 3 - 5 seconds to get a picture up on the screen. Now it seems to be taking 15 - 30 seconds to get up and running. The model I have this the LC-37GD4U. I am not that worried about it due to the Best Buy replacement warranty, but was wondering if this is something normal or perhaps I have it set up wrong. Let me know.
