It is a problem with your power supply board. It is most common on LCD tvs. If you know a little about electronics and soldiering you can fix it. What you need to do is take the back of the tv off and find the power supply board, easiest way is to follow the connector for you power cord up to it. Then i want you to look at the capacitors on the board, the are the cylinder looking things and they should have a metal top to them. Those tops are suppose to be flat, if any of them are raised that means that capacitor is bad. You can read the rating of the capacitor on the side of it and by new ones. I would suggest high temp 105 degrees C ones for tvs. To take them off its as easy as taking the board out, desoldiering the two connections on the bottom, pulling it off, and sticking in the new one and resoldiering it. Make sure when you put the new ones on that you line up the side with with the positive line to the same side that the old one came from, the positive line looks like a greyish stripe down the side of the capacitor. Do this to all that apply, you will need a desoldiering gun that cost like 10 bucks at a radioshack to take the soldier off properly.

Sharp LCD can't turn on

Bummer, one month out of warranty. This is why I always recomend keeping expensive, high tech stuff under warranty.
First thing to do is buy and download the service manual from and find out what the fail code of 1 blink means.

Green box keeps popping up in upper right corner

You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.
