1st Go through the settings and do a "Factory Reset" then make sure your connections good quality wires and not wrapped around or inter-woven with power connections etc. Also - make sure you don't have your speakers to close to the screen - this can cause discoloration and sometimes a shaking pic. Short of that - if it is new Return it for a working model.
Have a Sharp LC-42SB45U green light is on but no
This is the Actual solution, not a try this deal. You need soldering experience, and a multi meter. First pop the back case off the tv and look to the left, you'll see the inverter. It's got 8 or so pink and white connections on it and a few other wires and a ribbon cable. Take all of that off carefully. Now take out the screws that hold the board on. Once you have it in front of you look for the power connector on the far left above that you'll see two fuses. F1 and F2. Check both sides of F1 with an Ohm meter. Most likely it's blown. Replace this fuse with another one and your TV will be back running again. If you're feeling really clever you should touch up the cold solder joints on all of the inverters, and across all of the capacitors, some of mine were cracked.
