as soon as I turn on my proto trac 2xasis it has a loud contiuous noise bee bee noise same noise as if you press a button. it loads up fine on the screen but nothing will work if you press any buttons nothing happens. if I wait or keep turning it off and on it will eventually quite making the noise and work fine for a while then all of a sudden it will freeze up and the noise comes back then it will eventually stop and work again. Do I need a new one or can this be fixed and if so how much
