Missing/ Lost Remote
Most of the reset procedures listed on this website, require the use of the original factory remote - or one of the more sophisticated universal remotes, which have the possibility to access the enhanced features of the TV set (typically the button combinations to reset/access service mode are quite complex). If you've lost/damaged the original remote for your set you have a couple of options:
Ebay - Ebay
Cheap Universal Remote - 4 Device Universal Remote
Expensive Universal Remote - Logitech Harmony Ultimate Remote
