I have a 37 inch Magnavox LCD TV Model # 37MF331D/37 It is about 3 years old and It will not come on come on the indicator light is green and just blinks at times it seems like it want to go on and flash a blue screen slightly but then right back to black gray I check the fuse inside but it was good could it be the power supply? and if so where could i get one I can not seem to find it on line

Thank you so much for your time
