Menu button does not work

Hello! I'd be happy to help you.
To remove the key lock from your Grundig TV model GU26DVD without a remote control, you can try the following steps:

1. Turn on the TV using the power button on the TV itself.
2. Press and hold the MENU button on the TV for several seconds until the menu appears.
3. Use the volume up/down buttons to navigate to the "Lock" or "Child Lock" option and press the MENU button to select it.
4. Enter the four-digit password using the number buttons on the TV. If you don't know the password, you may be able to find it in the TV manual or by contacting the manufacturer.
5. Navigate to the "Off" option and press the MENU button to select it.
6. Press the MENU button to exit the menu.

If the above steps don't work or you don't have the manual to find the password, you may need to contact the manufacturer or a professional technician for assistance.

Reset the Drum Counter:
a. Press the MENU 1/Menu 2 button while turning the
printer on.
USER MNT appears on the display.
b. Press the MENU 1/Menu 2 button until the message
corresponding to the drum you are replacing
appears. For example, if you are replacing the
magenta image drum:
MAGENTA DRMCNT
RESET
c. Press the ENTER/POWER SAVE button.
RESETTING briefly appears on the display.
d. Press the ON LINE button.

Try this:

Under the menu options, there's Menu Lock. Switch it to "On". It worked for me.
My menu button wasn't working, so to access the menu, I had to hold down the arrow up button and push the arrow down button till I got to the Menu Lock Option.

The contact for the menu button may be stuck. It's at least five or six years old and may be on its last legs. If the menu button has shorted out, it may be more cost effective to replace it during Xmas sales. Check Amazon or Newegg.

hello..the problem is just sticky tack switch's so try to clean or re-align the frame/body of LCD..Thanks.Good Luck..^_^

run a nozzle clean, perform the following steps:

1. Verify the All-In-One Printer 924 is powered on and connected to a computer.
2. Verify that the paper support (input tray) has clean, plain white paper loaded.
3. Press the Menu button.
4. Press the Down button until Mode: Maintenance appears on the LCD screen.
5. Press the Menu button.
   The Dell 924 Maintenance Menu appears on the LCD screen.
6. Press the Down button until Clean Cartridges appears on the LCD screen.
7. Press the Start button.
   The AIO 924 prints the cleaning page. This process cleans the ink cartridges and resolves many print quality issues.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

try a recall button

Connect pin 1 & 5 together (momentarily with a small switch), on the remote control handset. with the tv already switched on, This will put the set into the engineering set up mode. You can step between the various options by using the -/-- button. the Mute button invites you to save your changes which I believe is saved when you next press the -/-- button. there are 18 different service pages in all, be very careful not to change things which should be left alone, as this menu controls the way this set operates. The menu button exits the service menu. I believe menu 13 should be the AV-SND options menu, you can select either DK-I-BG or M sound systems. only set one system to "on"at any one time. You may also need to check 14, the C- SYSTEM options Menu. Good Luck, A D.

the button is bad on it the select OSD button
the cable is bad, and tells you out range, no signal, or other cable dead errors or in sleep mode. can be PC, cable or monitor

Try pressing and holding the menu button for 15 seconds! That should unlock the controls! Regards, babb
