Lockout I have a mitsubishi 51 inch projection screen television that has its rfu connections locked out and im in desperate need of the lockout code

All computer monitors, whether they are LCD or CRT style, have a built-in feature called the on-screen display (OSD) lockout that prevents users from viewing any images on the monitor. If your computer screen has accidentally been set to the OSD lockout setting, there are several ways you can remove the lockout.

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.

Call Mitsubishi customer service first---to research this I would need the correct model number

is the button pysically broke... the unit does have a keyboard lockout feature press and hold menu for 10 seconds... maybe if not then the power button will need repair or a universal remote may be used

Go to this web site & download the user manual.

As silly as it sounds some Symphonic TV's use the code 0000 as a work around.

The keys on the front of the TV are probably in 'lockout' setting. Try holding the MENU key on the front of the TV for about 10-12 seconds to see if they will unlock. Let me know if this does not work.

Good Day, ariley1604;
Please contact comcast, and look into U- VERSE.
Good Luck, big IRISH.

that's a big problem. sometimes using the 0000 can unlock it but it's not 100 percent.try the trial and error.

have a tech lift off the eeprom or the microchip out of the set,that will rset your tv.and bring it back to normal.good luck.
