I need help with a VOOM box. I've been using a voom box as a OTA reciever, been working fine for a couple of years. Last week it started acting up, every time I flip to the local CBS station it turns the box off???? I've tried rescanning the channels, holding the reset button for 5 seconds then rescanning, unplugging the box for a couple days and rescanning, nothing. Is there any way to wipe out the scanned channels so I can to a fresh scan?
