I HAVE A HYUNDAI TV MODEL #HTV2020. TV SEEMS TO BE LOCKED ONLY A KEY IS ON THE BLACK SCREEN AND THE ONLY BUTTON ON REMOTE THAT WORKS IS THE ON/OFF. HOW DO I CORRECT THIS PROBLEM?

If you have lost the remote for your Telefunken 58" TV and you need to remove the lock key, you can try the following steps:

1. Locate the single button on the TV: Depending on the model of your TV, you may find a button labeled "Menu" or "Settings" on the side or bottom of the TV.
2. Use the button to access the TV's menu: Press the button to access the TV's on-screen menu. Navigate through the menu using the button to find the "Setup" or "System" options.
3. Disable the lock key: Look for an option in the setup menu to disable the lock key. The specific steps may vary depending on the TV model and firmware version, but you should be able to find the option to disable the lock using the on-screen menu and the single button.
4. Confirm the change: Once you have disabled the lock key, you should be able to access all of the TV's functions without being prompted for a password. Confirm that the lock key has been removed by trying to access a restricted function or channel.

If you are unable to disable the lock key using the single button on your TV, you may need to contact Telefunken customer support for further assistance. They may be able to provide additional information or instructions for disabling the lock on your specific TV model.

When an Insignia TV is locked, it keeps you from watching all of your channels by only displaying a black screen. Insignia TVs are locked from a single button command on the remote control, so it is easy for you to lock the TV by accident. Since Insignia TVs can be locked so easily, it's important to know how to undo this command and unlock the TV yourself. So, unlock your Insignia TV with the push of a button and once again enjoy watching your favorite programs.
• Find the lock button on the Insignia remote control. The lock button is located on the third column from the left on the second row from the top of the remote.

•Stand within operating range of the Insignia TV, then aim the remote at the TV's receiver and press the "Lock" button on the remote control.

• Aim the remote at the TV and press the channel buttons to make sure the TV is unlocked. When the TV is locked, it shows a black screen and does not allow you to view anything else. If the screen remains black, press the "Lock" button again. If this doesn't work, change the batteries in the remote and start over at step .

What is the make and model number of your flat screen tv.

my AKAI tv is locked. All i see is a blus screen with a little red lock on the bottom left corner! the only button that works on the tv OR remote is the power button on the remote. PLEASE HELP i have tried pushing every button but nothing happens

gonk,
Sorry but you're going to have to be a bit more specific than that.. What kind of Tv is it, what model number, is it the original remote, do you have an otherwise good pic and sound, do functions (vol, ch, power) on the Tv work???

It really sounds like the child lock has been activated. This uaually blocks the keys on the TV, but the remote should work. If your remote doesn't work either, make sure the batteries work. If your remote for the TV can operate other apliances such as a VCR or DVD player, make sure it is in TV mode. If there are any buttons marked TV, VCR, DVD you could try pressing the TV button to set it in TV mode. If the To has a text-tv function there might be more than one button marked TV; one for setting TV mode as posed to DVD operating mode, and one for getting TV picture back when viewing text pages. -Chris

hold down the display button for a few seconds
