My JVC AV-32F713 will not turn off. When I hit the power button on the remote, it blinks and the sound turns off. When I hit the power button a second time, it shuts off for a few seconds and then turns back on with the sound back on as well. I tried unplugging it for the night (for about 7 hours) and then plugged it back in to see if that would work but it did not. Any ideas?
