How to Troubleshoot a Big Screen TV

A big screen TV can give a movie theater feel to your living room. Most big screen TVs range in size from 42 inches to 61 inches. However, if you experience the unfortunate problems, follow the steps below to troubleshoot your big screen TV before calling a service technician.

Instructions

1. Check the power cord if your TV does not turn on. Plug it in, then press the power button on your TV or on your remote control. Replace the batteries of the remote control if the TV still does not turn on.

2. Reset your sleep timer options if your big screen TV turns off unexpectedly. Or, deactivate the wake up timer if it turns on unexpectedly.

3. Adjust the picture quality of your TV if you have picture problems, or if you can't get any picture. Select an input source by pressing the input feature on your TV or remote so that a picture appears on the screen. Find the "Picture" menu to adjust brightness, tint or color.

4. Choose mono sound if your TV's sound reception is poor, or choose stereo mode if there is no sound. Check your antenna and cable connections, and try a different channel in case there is a problem with the current channel. Make sure that the TV is not set to mute.

5. Verify that your TV is aligned with your cable or antenna source if you're having trouble getting more than 13 channels. Set the "TV/Cable" or a similar function on your TV so that you can properly access your cable service.

6. Turn off the closed caption feature if you have a black box on your TV screen that you don't want. Depending on your big screen TV model, it may be set to "text" mode. Use your remote or the controls on the TV to turn off closed captioning.
