I recently purchased a Visco 20" flat panel. It had been working fine until I had to unplug it when my cable service changed. When the cable company hooked me back up and I turned the tv on I can't get it to go out of standby mode. Nothing works, I changed the batteries in the remote and keep pushing the on/off button on the front but it stays in standby. Can anyone tell me what I can do or has anyone else had this similar problem. Thank you in advance for any help.
