I would search through for a similar post, but I simply do not have the time, so apologies if this has been answered previously. My young son got hold of the remote control and it looks like he set the channel lock. We don't have a lock code set, we've never used that option. The first time I saw it was when changing channels there was about 15 seconds of show then a black screen on which a blue box popped up asking for the pin. I can change channels, btu there is not even sound. I tried unplugging the box, several times. How do I unlock without a code?
