Hi, welcome to Just answer
Please tell me its complete model number and how old is it ?
Have you already tried to leave it unplugged for few hours and then plug it back again ?
Two flashing lights indicate problem with the power supply of the unit
how good are you with repairs ?
either ways it will be the power supply board that will have to be replaced
you can also contact Sharp at 08707 874837 for repair
