my 3 yr old lcd needs 15 to 20 minutes of a "warm-up' period each day of use. sound is gone or very staticy and you lose picture as well if you try to change channels before warm up period is done. need to turn off and on again if you lose pic to warm up. after 15 to 29 minutes of this, sound goes to normal, picture stays on and tv works as though nothing was wrong with it
