TroubleshootingTroubleshootingTroubleshootingTroubleshooting
If a problem arises while you are using the TV, please read this troubleshooting guide carefully before you ask to have the TV
repaired. You may be able to fix it easily by yourself. For example, if the mains plug is disconnected from the mains outlet, or the
TV aerial has problems, you may think there is a problem with the TV itself.
Important:
"This troubleshooting guide only covers problems whose causes are not easy to decide. If you have a question when you are
operating a function, read the page(s) for that function carefully, not this troubleshooting guide.
"If you follow the advice in this troubleshooting guide without any success, unplug the mains plug and ask for your TV to be
repaired. Do not attempt to repair the TV by yourself or to remove the rear cover of the TV.
