How do you open child lock in nobel tv and miss place the remot?

To open the child lock on a Nobel TV without the remote, try using the physical buttons on the TV itself. Look for a menu or settings button, then navigate to the lock settings using the volume or channel buttons. If that doesn't work, consult the user manual for specific instructions or consider resetting the TV to factory settings, which may disable the child lock. If necessary, you could also try using a universal remote as a last resort.
