It probably has a bad power supply. Unless you can do it yourself, it's usually cheaper to buy new than to repair.

If the set is not staying on, then the power supply is faulty and will need to be replaced. This is the box that the power cord is attached to.

Code for the one forall for a sharp tv


You do not need a code...
Heres how to set up your remete..
Turn on the devise you want to set up.
Press the set up key on the control firmly until the red light lites up and stays lit. Now press the key for the devise you are trying to set up(dvd, vcr, tv etc..).. the red light will now turn off.
Now facing the devise, begin pressing the power button several times until the devise turns off. Be careful not to press the power button any more after it turns off. After it turns off , you must immediatly press the enter key in order for the control to save the code. Now your control is set up. If this does not work , it is because you pressed the power button once more after the tv turned off....
This process might take you anywhere from 3 to 5 minutes.
