When attempting to identify a problem with your Philips plasma TV, perform basic troubleshooting steps endemic to every kind of TV before trying anything more specific. Check the power supply to make sure the TV is plugged in. Replace the batteries in the remote control with new ones, or change your position to give the remote a direct line to the set itself. Change the position of the antenna if the picture isn't clear, or contact your cable/satellite provider to tell them you're having problems. Check the connections on all of your cables to make sure they're secure: It sometimes helps to unplug them and then plug them back in to see if they'll work.

Can't Change Channels
Philips plasma TVs have a channel lock option, which lets you set one specific channel and change stations using a cable box or VCR.

Picture Distorted or Cut Off
Different TV shows are broadcast in different aspect ratios. If a show looks distorted or part of it is cut off, the Philips plasma TV is set to the wrong ratio. Press the "Format" button on the remote to access the available format choices, then select the one that provides the best picture for the show you're currently watching.
Instructions in a Foreign Language

You can then scroll up or down to reach the language you want and activate it by pressing the "OK" button.
