Why doesn't it turn on?

Well, apparently this is a huge problem with many flat screen TV's. They surpress the volume output from all external sources (like DVD players) so you don't blow up their tiny speakers. They just expect you to add on a home theatre system to boost the volume their small speakers cannot handle. This is a real problem if you are in a boat or RV and do no have the space or electrical capacity to do this. I had the TV checked out and Sharpe said it met their factory standards so there was no help there. We have had to go with a small amp & speakers just to hear the TV & DVD movies etc. They need to put better quality speakers in these TVs. The video is awesome, now work on the audio guys!

SOURCE: my tv will not turn on

your tv set is in auto protection mode.
sum times its due to a power line falur or a power surge to the set and other times its due to parts failing inside the set.
depending on the age of the tv, you might want a repairment to take a look at it.

I can tell you 100% that the problem that you are having will be a service issue. I can also tell you that your limited warranty covers in home service from sharp. Give them a call 1-87-SEE AQUOS(the advantage line that will get you through much quicker). or the 1-800-BE-SHARP and let them set you up for service, sharp will take care of that as long as the purchase date of your tv was within 1 year. If you dont want to go through that, I suggest taking the tv back to where you got it from if they will accept it because unfortunately, this problem can ONLY be resolved through service. good luck & keep me posted
