THE TV'S WERE BOUGHT AT AN AUCTION. I HAVE ABOUT 12 THAT ARE ON CHANNEL 3LCK. I HAVE THE ORIGINAL REMOTE AND THE MANUAL. THERE IS NOTHING IN THE MANUAL ABOUT LOCKING OR UNLOCKING CH3. I TALKED WITH THE MAINT. AT THE HOTEL THAT THEY WERE BROUGHT IN FROM AND HE DIDN'T HAVE A REAL ANSWER. THE CH3 LOCK WAS FOR THE HOTEL CABLE
FIRST........push MENU button 2 times......AFTER you push 2 times......push it again and THIS TIME hold it in until menu goes off..........then very fast push 9876 and ENTER button. You'll see your WHOLE screen with options. Scroll all the way up or down until its HIGHLIGHTED on the right side of screen. You want the very bottom "C10 AUX" push your RIGHT button until it says ON. Then turn TV off and back on. There you have it!!
