I hit a button on the menu and tv disappeared and I can't get the menu up again.

Power off your computer and then remove the monitor cable from the port on the back side of the computer case.

Reattach the cable and make sure the pins are correctly screwed in. Power the computer back on and check to see if the OSD lockout message is still being displayed.

Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lockout message.
Find the OSD lockout heading and read the method that your particular model uses to remove the lockout.
Attempt generic lockout removal procedures if you no longer have the manual that came with your monitor.

Press and hold the "Menu" button located at the bottom of your monitor for 15 seconds and wait to see if the OSD lockout message disappears.

Press the "Menu" button again if the lockout message remains on the screen.
Use the arrow buttons to navigate through the main menu options.
Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings.

Scroll down to the "OSD Lock" heading. Use the arrow keys to change the setting to "No." Hit the Menu key again to return to the main menu. Scroll to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lockout.

hope this helps

Its on a toggle switch. So hit menu, select time and day, do not hit exit, wait.
If it goes away, you just shut it off do this again, and it should stay on.

Hit the set up button on the TV.
You'll see options to change the language. The last option is to put the TV in "Demo Mode."
Put the TV in Demo mode, when the first screen appears, "Welcome to...." the PIP will disappear.
Hit exit before the screen moves to the "Menu." If you miss it, watch the demo once--it will restart--and hit the exit button the next time you see the "Welcome to" message.

I just did this and it worked for me - i hope it works for you.

Hit orange button in middle of remote: Menu comes up. Hit left arrow three times and you should see a menu with tuner mode at top. Hit down arrow to highlight tuner mode, use right or left arrow to select antenna or cable. Hit last button until menu disappears.
You're welcome.

I think that is the closed caption box. as you look at the front of the tv the ears are for up and down and the face is the menu button. hit the face once the menu will come up . then hit the down button to get to the close caption. then hit the up volume key to enter close caption. from there turn close caption off then hit the face key and that should do it.

I don't know the sharp(mfg) code to activate my universal remote

tell the idiots where u bought this tv from and demaand a more expensive and better tv on their bill

Ok,Who has been Playing with the Remote,Go into menu,And what you are looking for is Captions in the Captions mode look for Text,Turn it off,Just turn off cc Completly and that will fix it Let me Know ttech

On your remote should be a button called TV caption or text. Turn off the closed caption as someone hit it and turned it on by accident. If its not on your remote, then it is in the menu. Good Luck Ps Please dont forget to rate this thread.
