I have a minami tv,it is lock on only one channel.The volume and channel button is not functioning.My question is how to unlock it?

Your Apex TV has been locked by anyway. Just try this method to unlock it.
Apex TVs have parental locks that allow you to block certain programs based on
their rating. When this feature is no longer needed and you want your TV to display all programming no matter its rating, you must unlock your TV. Unlocking your Apex TV is done completely from your remote control and does not require any tools. The process takes less than 5 minutes.
• Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."
Use the arrow keys to switch the parental lock to "OFF." This allows all programs to be viewed no matter the rating. Press the "Exit" button on the remote and start watching all your channels.

Channels that have been locked can be viewed only when the PARENTAL CTRL function is set to OFF. This can only be done with the remote control-it can not be changed with the buttons on the front of the TV.

Therefore, after you turn on PARENTAL CTRL, you simply hide the remote control so that your children can not watch the locked channels. The locked-out channels will remain unviewable even if the TV is unplugged or the channels are autoprogrammed again. The only way to view locked channels is to use the supplied remote control to set the PARENTAL CTRL function to OFF.

The PARENTAL CTRL and the CHAN CTRL functions work hand-in-hand. The instructions below will first tell you how to turn parental control on or off with the PARENTAL CTRL function and then how to lock desired channels with the CHAN CTRL function.
1. Repeatedly press MENU to select SETUP MENU, and then press + or - to display setup functions. Repeatedly press MENU to select the PARENTAL CTRL function. . When this function is set to ON, PARENTAL CTRL is activated and any channels you locked with the CHAN CTRL function will not be viewable. . When this function is set to OFF, PARENTAL CTRL is deactivated and all channels are viewable.

2. To lock channels, press the MENU button to select the CHAN CTRL function. Select a channel you want to lock by pressing CHANNEL up or down. Then press +. The CHAN CTRL setting will change from NORMAL to LOCKED when that channel is locked. To return the channel to NORMAL, press the - button. Repeat step 2 for each channel you want to lock. If the PARENTAL CTRL function is set to ON while you are locking out channels, each channel will go blank as you lock it. When the PARENTAL CTRL function is set to ON and a channel which has been locked out is tuned, the TV will display the words PARENTAL CONTROL to let your kids know you have locked it.

TV's (Made by Daewoo or possibly Apex, ie. GE model 24GP653)
The factory default pass code of 6688 is also the override code, in case the owner forgets their pass code. If that doesn't work, another place in the owners manual says to push Function and Mute on the remote at the same time. Function is the top right button.

These are the general procedure to unlock a TV

Turn on the TV and grab the remote. In most cases, you will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.

Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.

Unlock all of the channels on the TV by entering the factory reset code. There are three main reset codes that TV manufacturers set. These are 0711, 6688 and 3308. Try each one until you find the one that works. This will reset the TV to original factory settings. When you do this, you will loose any information that you have stored in the TV, such as favorite channels, automatic timers and the clock. You will have to go through the full initial set up.

Call the technical support service number in your owner's manual if none of those codes work. A technician can help you troubleshoot the television because the problem may not be the locking control. When you call, make sure that you have the model number and serial number of the TV.

Take your television to a TV repair shop. In some cases, a professional who access to wiring diagrams for your television set may have to rewire certain components in order for the television to unlock. This is usually the case when the TV locks by itself while it is on.

Check this method too. If neither of them help you, check this link.

Disconnect the AC power for at least one minute to reset the clock.
Adjust the volume to the minimum using the Volume down button on the front of the unit.
Press and hold the Volume down button on the front of the unit and the 0 button on the remote control at the same time, holding them down for at least 10 seconds.
The user menu will appear with the V-Chip cursor blinking.
Press the ENTER key on the remote control and the NEW PASSWORD menu will appear.
Enter your new password.

Use the side panel buttons to unlock the TV Menu and side panel buttons:

1. Press the Menu button.

A message appears stating that the TV Menu and buttons are locked.
2.While the message is on the screen, press the volume decrease and channel up buttons on the side panel simultaneously. A message appears stating that the TV Menu and buttons are unlocked.
GOOD LUCK AND PLEASE RATE THIS POST!!!

you can lock/unlock above functions by pressing zoom and negative volume control keys simultaneously.

brendee89,
I did not get who the manufacture was of the tv but you may want to see if one or more of
the menue buttons are stuck down on the tv's front panel. This has been a common cause of
problems with Mitsubishi and Sony tv's. It could also cause volume to go up by it's self, no menue
functions, no power up and or no remote control functions to work.
Hope this helps,
Skyman

simply press the (function or F) button and the mute button at the same time. This will unlock the screen and allow you to view the channel as desired
