I have same problem with my LG flat panel lcd hd ready tv. I also noticed that when it is warm i dont have this problem but only on occasions when in my house is below 19 C, and it takes longer period to turn on if it is lower room temeprature.

the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!
