If your Westinghouse TV turns off and on unexpectedly, certain settings may unknowingly be activated. For example, if the sleep timer is on, your TV will turn off anywhere between 15 and 90 minutes after you initially turn it on. Power mode settings can either place the TV in a standby state or shut it down completely when you turn the TV off. Auto-source settings automatically switch connections when a new device is attached to it. Check all of these settings first to troubleshoot your LCD TV quickly.
