Try a few "universal methods" for unlocking the child lock. Some televisions have a universal code built in for disabling the child lock --no matter what your code is. A common code is "0000.". However, it might not work to some TVs. If you wish to get more details, surf the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the model name to your set in its search box, or view it in Timeslide / Mosaic option.

For the finisher error, follow above procudure, entering 14 instead of 16. if error returns, disconnect the finisher
