How to Troubleshoot a Westinghouse LCD TV That the Power Turns Off On

By Nina Nixon

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.

Step 1

Press the "Menu" button on the remote control or TV control panel. Press the left/right arrow buttons on the remote control to select "Settings" and then press "Enter." Alternatively, press the "Ch+/-" button on the TV control panel, and then select "Settings" and "Input."

Step 2

Press the up/down arrow buttons on the remote control or the "Vol+/-" buttons on the TV control panel to select "Sleep Timer." Press the "Enter" button on the remote control or "Input" on the TV. Select "Leave TV On" and then press the "Enter" button on the remote control to save your new settings.

Step 3

Access the "Settings" menu again. Select "Power Mode" from the menu. Press "Enter" on the remote control. Select "Energy Saving" and then press the "Enter" button on the remote control to save your new settings.

Step 4

Access the "Settings" menu and then select "Autosource" from the menu. Press the "Enter" button on the remote control. Select "Off" and then press the "Enter" on the remote to save your new settings.

Step 5

Access the "Settings" menu and then select "Reset All" from the menu if you're still having problems. Press the "Enter" button on the remote control. Select "Off" and then press "Enter" on the remote to load the factory defaults.

Tips & Warnings

  • Many Westinghouse LCD model TVs share similar troubleshooting steps.
  • You must run a channel scans again if you reset the TV back to its factory defaults. First, verify that the antenna is securely attached to the TV and then press the "Menu" button. Select "Channels," "Antenna Scan" and "Yes" to run the scan. When the scan is finished, select the "Channels" menu again and then select "Cable Scan" and "Yes" to run that scan.
