Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."

TVs Power Supply Unit may be faulty and you will have to get it fixed.
Opening up the TV may void the warranty.
Its better talk to TV Manufacturer's Tech Support.

gonk,
Sorry but you're going to have to be a bit more specific than that.. What kind of Tv is it, what model number, is it the original remote, do you have an otherwise good pic and sound, do functions (vol, ch, power) on the Tv work???
