Just purchase a mains power extension lead from any hardware store in the size you want. They usually start at about 3metres and go up in length from there.
Plug the extension lead into the power point and the power lead from the TV into the other end of the extension lead and there is your longer power lead.

You must replace power on/off switch.Best regards.

power supply is dead

Sounds like one or multiple Reservoir Capacitors in the Power Supply were starting to dry up. You also get problems like this from dry joints in the Power Supply. You need a technician to take a look for certain.
