you also can try this

1. Make sure the TV is plugged in but on standby
2. On your remote control locate 4 buttons
Info (below enter/ok)
Menu
Mute
Power
and press them in that order as quick as u can
TV should power up but with an on screen factory menu, push up twice on the remote direction buttons and highlight option 12 (Reset), hit ok and the TV will perform a factory reset, you will have to go through auto scan etc,
