It's a shame the age was not revealed but google this to learn why this is a known symptom of an issue or plague.

Most makers are covering this one.

LGE TV is taking longer and longer on start-up to display a picture. I may have to turn it off and on 7 or 8 times to get a pciture at all and it's getting worse. When I turn it on, the green light blinks and blinks and then goes steady, but no picture comes on. Then I have to hold in the Power Off on the TV to turn it off because it doesn't respond to the remote on switch off. Finally, after doing this for about 5 minutes, I get a picture. Occasionally a bright white light suffuses the screen but no picture appears. Finally, after turning it off and on many times, I get a picture but this problem is getting worse. Any ideas?
