Hello I have a realistic STA 2100 the monster unit I am having problems with it not coming out of safe mode when I press the power button and a click and stay read and won't click again and go to green I'm not much of a technician I would like to know is there inexpensive way to check and resolve this issue I find is unit too heavy to be lugging back-and-forth to a repair shop any help or suggestions would be appreciated thank you
