If a problem arises while you are using the TV, please read this ?Troubleshooting? well before you request having the TV repaired.
You may be able to fix it easily by yourself. For example, if the AC plug is disconnected from the AC 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 cause are not easy to determine. If a question arises when you are
operating a function, read the page(s) corresponding to the operation of the function well, not this Troubleshooting guide.
"After you have followed the Troubleshooting description or the operating description of the functions concerned without any suc-
cess, remove the AC plug from the AC outlet and request a repair of your TV. Do not attempt to repair the TV by yourself or
remove the rear cover of the TV.
